INDIANAPOLIS -- Green Bay Packers quarterback Brett Favre will undergo surgery this week, possibly as early as Monday morning, to remove bone spurs from his left ankle.

The pending procedure, which has been planned since the end of the season, was confirmed by Packers officials who are here this weekend for the annual NFL scouting combine.

The precise timing of the surgery might be determined by the weather in the Green Bay area, the Green Bay Press-Gazette reported, and by Favre's ability to fly there from his Hattiesburg, Miss., home.

Favre, 37, faces a rehabilitation period of 8-10 weeks after the surgery, which will be performed by Dr. Patrick McKenzie, the team orthopedics specialist. By undergoing the surgery in coming days, Favre should be fully recovered in time for the Packers' first spring minicamp, which will begin May 20.

Earlier this month, Favre announced that he will return for his 17th NFL season.

The surgery is aimed at alleviating longtime pain and swelling in Favre's ankle. Doctors have recommended to Favre that he have the surgery after each of the last few seasons, but he had put it off each time. In announcing his plans to return for the 2007 season, Favre said he would finally undergo the surgery in an effort to enhance his mobility.
