Walker (undisclosed) is active for San Francisco's Week 12 matchup at the Rams.
Walker spent nine days on the reserve/COVID-19 list between Nov. 19 and Nov. 28, but he didn't have to miss any game action with San Francisco taking its bye over Week 12. Because of Demetrius Flannigan-Fowles (hamstring) being ruled out for Sunday's contest, Walker is in line to get the start at weakside linebacker.
