Drew Brees doesn't know how bad the thumb injury that knocked him out of Sunday's game is, but he conceded that he's worried.

"Yeah, I am concerned. I'm hoping it's not too significant," he said.

The New Orleans Saints quarterback plans to see renowned hand specialist Dr. Steve Shin in Los Angeles.

"I really don't know at this point. There's only so much you can do here other than have a doctor look at it on the sideline," he said.

Brees left late in the first quarter Sunday after his right (throwing) hand hit Los Angeles Rams defensive tackle Aaron Donald's hand at the end of an incomplete pass.
