While the San Francisco 49ers might be getting one of their best threats back in action on Sunday in kick/punt returner Ted Ginn Jr., the Minnesota Vikings are ruling players out. Linebacker Erin Henderson was ruled out of Sunday's game with a concussion, which wasn't known about until Wednesday. Henderson didn't feel right and has missed practice since that point, and definitely will not be in action on Sunday.
On top of that, defensive end D'Aundre Reed was ruled out for the game with a calf injury. Reed was inactive all of last season, but managed to play in Minnesota's first two games. Minnesota also had five players listed as probable for the game, the most notable of which is defensive end Brian Robinson. They're already running low on defensive players, so his absence would definitely be missed.
In good news, center John Sullivan and cornerback Chris Cooke were full participants in Friday's practice and have been removed from the injury report. Below, we've got the official report:
Out: LB Erin Henderson (concussion), DE D'Aundre Reed (calf)
Full Practice/Removed From Injury Report: C John Sullivan (ankle), CB Chris Cooke (biceps)
