Head coach Kyle Shanahan said Campbell wasn’t expected to play for the Niners again this season after he refused to enter the game in last Thursday’s loss to the Rams. While many thought the Niners would release Campbell in the coming days, the Niners have instead opted to end his season with this three-game suspension. Campbell signed a one-year contract with the Niners this offseason to replace linebacker Dre Greenlaw, who suffered a torn Achilles in the Super Bowl, but his role on the team had diminished in recent weeks with Greenlaw on the mend. Campbell totaled 79 tackles, three TFLs, and two pass breakups in what is certain to be his only season with the team.

Campbell refused to enter Thursday’s game in the third quarter and then walked off the field. The 49ers could choose to suspend Campbell for the rest of the year instead of cutting him, though the result is functionally the same. Campbell has played his last snap in San Francisco.

Alrighty then. A returning Dre Greenlaw (achilles) felt achilles and knee soreness and had to check out. Coach Kyle Shanahan called on free agent addition Campbell and he refused to play. His teammates were in disbelief afterward, saying they expected Campbell to get cut. Second that. Campbell has been a regular this season, playing 719 snaps entering Week 14. It won’t be easy to replace someone at this juncture, but he will definitely be waived, likely on Friday.
