SANTA CLARA, Calif. – Although no move has been made official, San Francisco 49ers coach Kyle Shanahan made it clear Friday that linebacker De’Vondre Campbell has played his final snap for the team.

Campbell’s decision not to play in Thursday night’s loss to the Los Angeles Rams angered Shanahan and many of his teammates. After the game, Shanahan and several players made it clear that Campbell’s actions were unacceptable, with cornerback Charvarius Ward even saying that Campbell would “probably be out soon.”

As of Friday morning, the Niners have not determined exactly how they will part ways with Campbell, but Shanahan said he does not expect Campbell to be with the team in Week 16 and beyond.

“We’re working out the semantics to deal with exactly that,” Shanahan said. “But I mean, you heard from me last night, you heard from our players, his actions during the game, this is not something you can do to your team or your teammates and still be part of our team. We’re currently working on the exact semantics of this, but we will address the situation appropriately.”

The most obvious move would be to release Campbell outright, making him an unrestricted free agent and having the freedom to sign with another team immediately. However, there are other options the Niners can explore, such as a suspension without pay for behavior that is detrimental to the team.

Campbell signed a one-year, $5 million contract with the Niners in March, meaning he will be an unrestricted free agent again after the season regardless of what the 49ers do now. When Campbell signed, the Niners envisioned him as a placeholder for Dre Greenlaw, the team’s weak-side linebacker who was recovering from a torn Achilles tendon in Super Bowl LVIII.

A deal with Campbell came about after another veteran linebacker, Eric Kendricks, agreed to sign with San Francisco before moving to the Dallas Cowboys. While Greenlaw was still recovering through the first 13 weeks, Campbell started 12 games and played 90% of the defensive snaps with 79 tackles, including three for losses and two passes defended.

“We needed an experienced linebacker to fill in for Dre until he could come back,” Shanahan said. “We didn’t know how long it would take. I thought he had some ups and downs throughout the year. He improved as the year went on.

Greenlaw’s return Thursday night provided an immediate spark for the Niners’ defense, which held the Rams without a first down in the first quarter and to just three points in the first half. But Greenlaw began dealing with knee soreness in the third quarter when the Niners asked Campbell to come into the game.

According to Shanahan, Campbell was actually asked to come into the game in the second quarter when strong linebacker Dee Winters left with a neck injury. Demetrius Flannigan-Fowles had to step in for Winters after Campbell told the coaching staff he didn’t want to play.

Shanahan said Friday that he didn’t go back to Campbell until the third quarter and figured out what was going on himself. Shanahan said Campbell was away from his teammates and “distanced from everyone” when he approached him.

“I didn’t realize it until the third quarter when Dre came out and Dee came in, and then I put the defensive headset on and asked what was going on,” Shanahan said. “And then the coaches told me, and then I approached De’Vondre and found out. It was pretty easy to see how he was doing and we moved on with our lives after that.”

Shanahan added that he did not tell Campbell to go to the locker room in the fourth quarter, a walk that was shown on the television broadcast as it occurred. Shanahan added that he wasn’t sure what led to Campbell going to the locker room, but “when I found out he wasn’t playing, I moved on to people we could count on.”

With Campbell on his way out, the Niners will likely need to add another linebacker to the roster. Shanahan said Friday that Greenlaw (knee soreness) and Winters (neck soreness) will be day-to-day when the team returns to practice next week.

But assuming Greenlaw recovers well, he will continue to keep his usual starting spot. For his part, Greenlaw said after the game that he didn’t really know what was going on with Campbell but didn’t seem too worried about it.

“He didn’t want to play,” Greenlaw said. “I think if he didn’t want to play, you don’t have to play. So he didn’t want to play.”
