Wilhoite had been banged up for much of the season, and Davis will likely get a shot to turn some heads in Week 17.
The San Francisco 49ers made a roster move on Saturday, activating running back Mike Davis off the injured reserve list. To make room for Davis, the team placed inside linebacker Michael Wilhoite on injured reserve.
Davis suffered a hand fracture, and was placed on injured reserve on November 7. The team used their single "return designation", which allowed them to bring him back this week. Davis returned to 49ers practice two weeks ago, and this week marks the time the team could activate him off the list.
