EDEN PRAIRIE, Minn. -- Officially, Minnesota Vikings defensive end Brian Robison is probable for Sunday's game, after practicing on Thursday and Friday with what's listed as a "glute" injury.

Robison was hoping the team would describe it differently.

"I would have personally rather it had been called 'buttocks,'" he deadpanned on Friday afternoon.

He has no choice but to stay in good humor about the injury, which occurred when he took a knee to the hindquarters on Sunday in Tampa and has become something of a tourist attraction in an NFL locker room, where sophomoric humor is always welcomed.

"What's funny about it is everyone wants to see it again. It's kind of awkward," Robison said. "It's almost every morning I come in here, I have to walk around with my pants down because everyone wants to see it every morning to see if it changes."

Robison played 40 snaps on Sunday against the Buccaneers, which was his lowest total of the season, while dealing with the injury. In all seriousness, considering how much of am NFL player's power comes from his legs and gluteal muscles, the injury couldn't have been pleasant for Robison to play with, though he said it didn't bother him in practice on Thursday or Friday. The worst part of his day, Robison said, comes from sitting down.

Let's just say Robison made sure reporters got a chance to put his injury in proper context on Friday, and with that in mind, coach Mike Zimmer's description of it -- "he's got a bruise on his butt cheek," Zimmer said Thursday -- is understating the case somewhat.

"It's slowly spreading," Robison said. "It's going to be fun to watch this thing grow."
