Panthers QB Matt Moore, who left Sunday's loss to the Giants with a concussion, was back on the practice field on Wednesday.
It remains very possible that Moore will start Sunday's game against the Buccaneers. Head coach John Fox said Moore looked "just like normall Matt" even though he said that Moore remains "day to day."
Fox often characterizes all non-season-ending injuries as being of the day-to-day fashion.
Moore suffered the concussion on a sack in the fourth quarter near his own end zone.
If Moore can't go, the Panthers would turn to Jimmy Clausen, who made his NFL debut on Sunday (0-for-2 passing) in relief of Moore.
Moore struggled in the opener, throwing three interceptions and losing a fumble.
