How quickly can Roos recover?

Titan left tackle Michael Roos had an appendectomy on Monday morning.

Will he be back and ready to matchup against Dwight Freeney, or Robert Mathis, of the Colts on Sunday?

I asked ESPN’s resident physical therapist Stephania Bell, who gave it a definite maybe.

“To me it seems tough to be able to do what he needs to do on the line that quickly,” she said. “I never say never with medicine … look at what some guys are doing these days. But it wouldn’t surprise me if he missed a week."

She pointed to Pittsburgh quarterback Ben Roethlisberger and baseball outfielder Matt Holliday for comparison.

Roethlisberger had an appendectomy Sept. 4, 2006. He missed the Steelers’ Thursday night season-opener but returned to action on Sept. 18.

Holliday returned to action in nine days in 2011.

“As a tackle, the demands are different," Bell said. “Lot of resistance work through the trunk."

It seems to me Roos has been playing better in recent weeks after a slow start. There will be a giant drop-off if the Titans have to turn to backup Mike Otto against Indianapolis.
