Panthers WR Adam Thielen (ankle) did not practice on Thursday. That follows Wednesday's limited practice. This could have been a planned day off for Thielen. But, more likely, he hurt that ankle on Wednesday and is now in danger of missing this weekend's opener vs. the Falcons. WR D.J. Chark (hamstring) remained sidelined on Thursday. Rookie WR Jonathan Mingo could be in for a busy debut.
