Safety Tyrann Mathieu is going to miss some time with his shoulder injury, but he was in good spirits Tuesday after the Cardinals had meetings and their annual team photo. Mathieu hung out with some teammates in the locker room for more than an hour after the photo and said his mindset was "pretty good" even though he got hurt.

"It's not something that's going to keep me out for the rest of the season," Mathieu said, echoing Bruce Arians' thoughts previous.

Mathieu said he was in on a tackle trying to pull a Panther down and in the course of trying to brace himself, both his weight and the Panthers player's weight fell on his arm.

"I kind of popped it back in, and then it felt like I lost some strength in it," Mathieu said. "I played one more play and then I was like, 'This doesn't feel right.' "

Mathieu left after playing 16 defensive snaps. He was originally listed as probable to return, but he did not. Arians said Mathieu could miss up to 3-to-6 weeks, but Mathieu said he was hopeful it would more like 2-to-3. Arians seemed certain Mathieu would miss the Cardinals' next game Nov. 13 at home against the 49ers, but there is a chance Mathieu could be back for the Nov. 20 road game in Minnesota. Mathieu will have to play with a harness once he returns.

"Once my shoulder gets stable, I'll be good to go," Mathieu said.
