After Sunday night's game, Mark Sanchez appeared groggy. Talking to reporters, he paused a couple of times in mid-sentence and turned away when a TV light shined in his face. He was asked if he had a concussion; he said he was fine.

The team's medical staff apparently had questions, too, because they tested him for a concussion.

On Tuesday afternoon, Sanchez filled in some of the blanks during his weekly spot on "The Michael Kay Show" on 1050 ESPN Radio. Sanchez said he "did some balance tests and stuff like that ... some baseline stuff" on Sunday and Monday.

"They checked my baseline tests and compared it to my balance test and everything now," he said. "I feel good."

Asked if he was concerned he had a concussion, Sanchez said, "No, I don't think so. I just think they were being really cautious."

On Monday, coach Rex Ryan said Sanchez "seemed fine to me," adding that he wasn't on the treatment list.
