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. General Manager John Lynch officially said Campbell
was suspended for conduct detrimental to the team. 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.
