ALLEN PARK, Mich. — After an offseason full of notable free-agent signings and surprise draft picks, the Lions gathered together for Day 3 of OTAs — this time, with an audience on hand.

Thursday’s session was open to local media. There were plenty of new faces working to earn jobs and their place on this team. But it was also a good reminder of the reinforcements the Lions have on the way who weren’t able to contribute to last year’s success. There’s a lot of buzz around this team right now, in part because the roster is the deepest it has been since Dan Campbell and company arrived in 2021. At the same time, he knows that integrating pieces new and old will be a challenge itself.

“Right now, everything is about the work, and it will be when we get into training camp,” Campbell said. “We’ve got a brand-new team that we’ve got to build from the ground up again. Yeah, we’ve got a foundation, but yeah, man, we’ve got to get the chemistry right, we’ve got a lot of new faces. And all of that other stuff won’t matter if we don’t put the work back in. So that, to me, is the focus.”

That’s what this time is about.

Much of the offseason has been good news for the Lions, between keeping Ben Johnson, the moves made in free agency, the draft and the overall outlook for the team in 2023. However, Jameson Williams’ looming absence remains large.

Williams was suspended six games last month for violating the NFL’s gambling policy. Williams placed a bet on a non-NFL game from an NFL facility — which includes the practice facility, as well as hotels, planes and buses on road trips. Williams, speaking to reporters for the first time since his suspension, said he was not aware of the league’s rule that bans such activity, but owned up to his mistake. He spoke for roughly 10 minutes and answered every question asked of him.

“I was sick,” Williams said of his reaction to the news. “I was hurt.”

A couple of notes:

• Williams said he didn’t know where he was when he placed the bet that ultimately led to his suspension.

• Williams said he found out about his suspension the night before the announcement.

• When asked about the NFL, which partners with gambling companies, suspending him for gambling on non-NFL games, Williams said: “That’s really not my decision. I’m in the league to play football, not make the rules on gambling.”

• Williams said he’s using this time to focus on his craft and fixing the little things with his game before his suspension begins in September.

There is no appeal process for Williams’ suspension, so this time with the team is important. Williams, recovering from a torn ACL last May, couldn’t practice a year ago. Thursday, he was out there running around, showing off that signature speed on a few downfield shots, providing glimpses of why the Lions drafted him in the 2022 first round. That game-breaking speed is very much present, but because of the time missed, it has become secondary to everything else. The Lions would love nothing more than for the Williams narrative to shift back to his skill set.

“Look, he knows,” Campbell said. “I mean, he’s gotten it from everybody. And so, look, it happened. It’s an emphasis in the league right now. It’s a big thing. Our players know. We’ve tried to hammer it home. Certainly we did after that point and a few more times and we’ll just keep doing it. But listen, it’s happening. The suspension is happening, and so now what do we do to move forward? You’re not going to be here, so in the meantime, let’s get the most work we can out of you.”

Tracy Walker returns to action

Every now and then late last year, you could find Tracy Walker hobbling around on crutches and a boot in the Lions’ locker room.

Players would gravitate to Walker, especially the younger ones. Walker was Detroit’s defensive captain and, at the time of his injury, one of its few vocal leaders. His absence was felt on the field and in the facility. For Walker, meanwhile, those random appearances in the locker room had to have been therapeutic, perhaps reminding him what he was working toward, and how much he wanted to be back.

Walker said then he’d be back in time for OTAs. Along the way, he posted videos of his rehab process and on-field work, all with a May return in mind.

In the end, he kept his word.

“I’m built different,” Walker said after Thursday’s practice. “I stand on that. I know I’m not built like nobody else. I live by it in everything I do, from how I work, how I grind and obviously my injuries. I’ve never been hurt before, so for me to bounce back, that was the main thing I had on my mind.”

Walker didn’t participate in everything Thursday, heading to the sidelines during scrimmage periods, but he did pretty much everything else for which he was cleared. The fact that he’s out there at all seven months after a torn Achilles is a testament to his work ethic. Walker said he felt for his teammates during a five-game losing streak that dropped them to 1-6. But he also didn’t get to contribute to the 8-2 stretch to end the year — the very reason expectations are high right now. That’s why Walker is so eager to get back to work. Last year was Walker’s first winning season in the NFL and he missed the majority of it.

He’s expecting to be fully cleared by the start of training camp. He’s a projected starter in a revamped secondary, one that’s closer in talent to the group with which he entered the league.

Top Lions position battles as OTAs begin: How do the new players fit in?

There was a moment last year, as he recovered from back surgery that kept him out of action in 2022, when Halapoulivaati Vaitai considered retirement.

It didn’t last long, though. Too much time on his hands.

“It was just a bunch of stuff to do,” Vaitai said. “I’m like, ‘What am I doing?’ I couldn’t decide what to do. The only thing I know is football.”

Vaitai, the Lions’ starting right guard, said being away from the team was eating him alive. He was having a great training camp before going down. The Lions scrambled to replace him, playing center Evan Brown at guard and living with the results. But Vaitai’s return could be the missing piece for an already strong offensive line.

Vaitai practiced Thursday and said he feels great. He’s expected to maintain his starting job at right guard. The Lions will be smart with him during this period, but when training camp starts, they’ll turn things up. This staff still values what he brings to the table in terms of run-blocking and mentorship to younger guys like Penei Sewell. Vaitai, meanwhile, wasn’t quite ready to let go of this game and leave what has been building in Detroit.

“I can’t leave Penei, I can’t leave all my guys, I can’t leave them,” Vaitai said. “I love this team a lot and I want to help Dan win one. ”

Observations, news and notes

• The Lions began practice splitting up team reps on the two fields. It looked like ones versus ones on one field. I watched the defense Thursday and made note of the first team: Aidan Hutchinson and Charles Harris on the edge, Alim McNeill and Christian Covington at defensive tackle, Alex Anzalone and Derrick Barnes at linebacker, Will Harris at nickel, Jerry Jacobs and Cam Sutton at outside corner and Kerby Joseph and C.J. Gardner-Johnson at safety.

• The first rotation of linebackers featured Anzalone at Mike and Barnes at Will. The Lions rotated quite a bit, with Jack Campbell and Malcolm Rodriguez getting first-team reps, too, so it’s probably not worth reading too much into. Anzalone is capable of playing the middle or weakside linebacker role, so this was probably a case of the Lions splitting the work up. Campbell has to earn the starting job, but it feels like it’ll be his before it’s all said and done.

• Speaking of Campbell, he was part of an impressive play Thursday, but not for the reasons you’d think. During a scrimmage period, running back Jermar Jefferson caught a pass, made a man miss then sprinted toward the end zone. A solid play, but the more impressive part of the play was Campbell chasing him down, when every other defender gave up and prepared for the next snap, all the way to the end zone. Toward the end of the run, Campbell was nearly stride for stride with Jefferson, who couldn’t help but laugh when he saw Campbell that far downfield with him. The takeaway: Campbell’s long speed is impressive for a guy his size. So, too, is the max effort he gives each rep.

• McNeill looked noticeably trimmer and lighter on his feet, which was one of his offseason goals. He changed his diet, improved his flexibility and took a more professional approach entering his third year in the league. He wants to be more consistent and prove the flashes of dominance he showed at times (like the Giants game) could become the norm. Once thought of as a nose tackle, the Lions let McNeill play more three-technique as the year went on. Expect that to continue.

• Speaking of defensive tackles, Levi Onwuzurike was spotted at practice, though he was unable to participate. He was in uniform but no helmet. A back injury wiped out Onwuzurike’s second year in 2022, and updates on his progress have been few and far between. Perhaps Thursday’s appearance is a sliver of hope.

• Cornerback Emmanuel Moseley, who’s still recovering from a torn ACL, did some individual work without a helmet. That’s a good sign. Jacobs and Sutton handled first-team reps at corner.

• Center Frank Ragnow, guard Jonah Jackson, and defensive tackles Isaiah Buggs and Benito Jones were among the players not spotted at Thursday’s OTA session.

• The Lions traded a conditional 2026 seventh-round pick to the Jaguars for kicker Riley Patterson. Patterson was a starting kicker for the Lions in 2021 before losing a battle to Austin Seibert in the preseason last year. Patterson connected on 30-of-35 attempts with Jacksonville last season. Seibert was waived by the Lions in October. The Lions now have Patterson, Michael Badgley and former XFL kicker John Parker Romo in the mix at kicker.
