The San Francisco 49ers were barely hanging on in the playoff race, and desperately needed a win Thursday night against the Los Angeles Rams to stay afloat.
And in the second half of a tight game, linebacker De'Vondre Campbell decided he was done playing.
Niners head coach Kyle Shanahan told media after the game, which the Rams won 12-6, that Campbell, a nine-year veteran for the 49ers who had started 12 of 13 games this season before Thursday night, told the team he didn't want to play. Campbell went to the locker room in the second half.
