Robert Quinn was admitted to a hospital on Monday morning with a non-football-related injury.

Quinn later did interviews with the media, but he admitted himself to a local hospital shortly after the team returned to the west coast late Sunday.

Jeff Fisher wouldn't go into details regarding Quinn's medical condition but said it's "highly unlikely" that it is related to the benign brain tumor he was diagnosed with in high school.

"He's feeling much better," Fisher said during his weekly availability from the team facility late in the afternoon. "He kept saying to me over and over, 'Coach, I just want to get back, get my mind right and get back on the field as fast as I can.' We're still undergoing tests. Things look encouraging."
