It’s no longer an injured quad that’s slowing L’Jarius Sneed’s return to the practice field.

It’s a knee issue.

Titans General Manager Mike Borgonzi revealed Tuesday that Sneed in May underwent what he termed a clean-up surgery on his knee, which is the reason Sneed will begin training on the team’s physically unable to play list (PUP).

Center Lloyd Cushenberry (torn Achilles), as expected, will also begin training camp on the PUP list.

Borgonzi classified each player as week to week, with training camp getting underway Wednesday morning.

In other injury updates, Borgonzi said wide receiver Treylon Burks and rookie safety Kevin Winston Jr., both of whom are recovering from torn ACLs, are completely healthy for the start of camp.

One other personnel update: Borgonzi said veteran edge rusher Lorenzo Carter, who signed with the Titans in March, told the team Monday he would be retiring after a seven-year career.

Carter’s departure from the game will be another blow to a thin edge rusher group, behind Arden Key, Dre’Mont Jones and rookie Femi Oladejo.

Sneed, who signed a four-year, $76.2 million deal with the Titans in March 2024, missed the last 12 games of the 2024 season with a quad injury. He also missed all the 2025 offseason, with what most believed to be the lingering effects of the quad injury.

But Borgonzi said Tuesday the knee, which required a practice maintenance program for the past two seasons, is now what Sneed is working to overcome.

“He’s making progress,” Borgonzi said. “He’s really worked hard. He’s been here during the summer. He’s headed in the right direction. We’ll hopefully get him back here soon.”

Is it common for a clean-up procedure to keep a player sidelined at least two months after the surgery?

“I keep in contact with [Sneed] all the time,” Borgonzi said. “He’s worked really hard to get back, and I feel really confident he’s going to be back.”

In the meantime, the Titans have been busy collecting cornerbacks since the end of the 2024 season.

They drafted Cal’s Marcus Harris in the sixth round and signed free agent Amani Oruwariye. A six-year veteran, the 29-year-old Oruwariye has played in 61 NFL games, making 40 starts and recording 10 interceptions.

The Titans also added four undrafted free agent corners following the draft: Jermari Harris (from Iowa), Jalen Kimber (Penn State), Clarence Lewis (Syracuse) and Davion Ross (Memphis).

Might even more corners be needed on the roster, given Sneed’s health status, as well as the fact he’s the target of a $1 million lawsuit over an alleged shooting incident?

“I think we’ve got a lot to do at a lot of positions, not just corner,” Titans president of football operations Chad Brinker said. “We’ll continue to evaluate this every single day. We’re going to look at other opportunities to upgrade the roster when we can. If we’re able to do that, we will. But we’ve got some work to do, not just at the corner but other positions as far as depth is concerned.”

Cushenberry, who missed the last nine games of last season, sat out the entire offseason as well following the Achilles injury.

Corey Levin will likely take most of the first-team reps at center as camp gets underway, but it’s important that Cushenberry and rookie Cam Ward — the presumed starting quarterback — get some time together before the season gets underway.

“I think that’s important,” Borgonzi said. “Hopefully he’s going to be back here soon. He’s week to week and he’s making really good progress.”

Burks missed the last 12 games of last season following the torn ACL last season.

The 2022 first-round pick is heading into the final year of his contract, after playing just 27 games and making 53 catches in his first three seasons.

“He works really hard,” Borgonzi said. “I know he’s a talented kid. He’s just had some setbacks in his career so far. But he’s been out there working. I saw the shape he came back in [Tuesday], which means it’s important to him. I look forward to seeing him here in person.”
