Yet, Pro Bowl linebacker Ahmad Brooks is dressed like he's still playing in Green Bay nearly two weeks ago.
Fighting a "severe head cold" that kept him from practicing Wednesday, Brooks went through the 49ers' walk-through practice Thursday morning and was on the field for practice later in the day. Brooks said he's been dealing with the illness for a few days.
He was dressed for inclement weather, including a head wrap that covered his month. He was wearing layers and gloves to help him sweat.
"I'm feeling all right," Brooks said between workouts. "Just got a head cold, a severe cold. I'm trying to sweat it out as much as possible and get ready for the game."
Barring a major setback, Brooks should be able to play Sunday. He has 4.5 sacks in the 49ers' two playoff wins.
