The Panthers activated Wharton (neck) from the reserve/PUP list Saturday.
Wharton had his 21-day practice window opened Tuesday and remains listed as questionable for Sunday's game against the Eagles. The 28-year-old has appeared in just nine of a possible 21 regular-season games since the beginning of last season. He logged 36 tackles (11 solo), including 2.0 sacks, and a pass breakup across nine appearances last regular season.
