Panthers' Kamu Grugier-Hill: Tending to groin injury

Grugier-Hill (groin) was a limited participant at practice Wednesday, David Newton of ESPN.com reports.

It's not clear when Grugier-Hill picked up the groin issue, but it puts his availability for Week 18 in danger either way. He'll probably need to log a full practice Thursday or Friday in order to avoid carrying an injury designation into the weekend.
