Panthers linebacker Shaq Thompson, the team's first-round pick, sat out Wednesday's practice with a hamstring injury that is not considered serious.
Panthers coach Ron Rivera said it's the same issue that bothered Thompson during minicamp in June after he'd missed most of OTAs while finishing classes at the University of Washington.
"It was a little tight the last couple days, so (trainers) felt the best thing was to be careful, be smart with it," Rivera said.
Thompson was one of several defensive players who were out.
Defensive tackle Kawann Short (back) and cornerback Bene' Benwikere (hamstring) have yet to practice during training camp, while defensive tackle Star Lotulelei is sidelined a few weeks with a stress reaction in his surgically repaired right foot.
Rivera said he hopes to get most of the injured players back for the Panthers' joint practices against Miami on Aug. 19-20, although he conceded Lotulelei might need more time to heal.
