In response, the 49ers have opened the practice window for rookie linebacker Tatum Bethune.
Typically, this move initiates a 21-day period for the team to activate Bethune off injured reserve. However, with only two games left in the season, it's unclear if Bethune will be activated in time for Monday night's matchup against the Detroit Lions. The decision could simply be an opportunity for the young defender to earn additional practice reps before the offseason.
The 49ers selected Bethune in the seventh round of April's draft. This season, he has played just eight defensive snaps, recording two tackles and a fumble recovery, but he has more on special teams, logging 130 snaps.
Bethune was placed on injured reserve on November 23 with a knee injury.
