Minnesota Vikings quarterback Brett Favre underwent arthroscopic surgery on his injured left ankle Friday morning.

Noted orthopedic specialist Dr. James Andrews operated on Favre at the Andrews Institute in Gulf Breeze, Fla., where Favre and his agent Bus Cook were spotted by a handful of people.

Favre confirmed the procedure on his website.

"This is to confirm that I did have a procedure to remove some scar tissue and bone spurs from my ankle which had been bothering me for a period of time. I appreciate your concerns," Favre's statement read.
