Minnesota Vikings quarterback Brett Favre underwent arthroscopic surgery on his injured left ankle Friday morning, several sources told ESPN.com.
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.
Dr. Andrews cleaned up scar tissue and other elements of the joint to allow Favre a better range of motion, sources said.
A source close to Favre said the 40-year-old signal caller would likely need four-to-six weeks of rehabilitation before beginning a running program that would put him on schedule to report to training camp "either at the beginning of camp or shortly thereafter."
Favre had previously said he would need the surgery if he were going to play in 2010. He was unavailable for comment.
Now that several sources are confirming, we are almost ready to believe that Favre did indeed have that ankle surgery today. If everything checks out, the odds of Brett Favre returning to the Vikings for the 2010 season have increased.
