San Francisco 49ers linebacker De’Vondre Campbell refused to enter Thursday’s game against the Rams, according to head coach Kyle Shanahan.

Campbell was spotted heading into the locker room during the third quarter of the 12-6 home loss. When reporters asked Shanahan about this, he replied, “He said he didn’t want to play today.”

The coach clarified that this conversation happened in the third quarter, when Campbell was asked to come in for Dre Greenlaw, who was dealing with Achilles fatigue and subbed out of the game. Shanahan added that this was the first time in his career that a player had quit on him in the middle of the game.

A clearly stunned press corps continued to pepper Shanahan with questions about this incident. One reporter asked what the coach needs to do to make sure he doesn’t lose anyone else in the locker room, and Shanahan replied firmly.

“Haven’t lost anybody,” Shanahan said. “That's somebody who doesn't want to play football anymore, it's pretty simple. I think our team and myself, we know how we feel about that, so I don't think we need to talk about him anymore.”
