Mariners left-hander Cliff Lee underwent minor surgery on his left foot last Friday in Little Rock, Ark., the club announced on Monday.

The surgery, which was performed by Dr. Bryan Burke, removed a floating bone spur in Lee's left foot that broke from its attachment. The procedure will not require Lee to wear a cast. He's expected to return to normal baseball activities in the next two to three weeks, which means Lee will be unable to participate in workouts when Mariners pitchers and catchers report to camp in Peoria, Ariz., on Feb. 18.

"We decided Lee should have the surgery as soon as possible, rather than try to pitch with the discomfort during the year," general manager Jack Zduriencik said. "To get it out of the way and have it behind us is important."

The surgery alleviated "irritation and discomfort in the joint and surrounding tissues," the release read. For the next seven to 10 days, Lee will be able to bear weight on the left foot and continue his upper-body exercise program.

Lee was acquired by the Mariners on Dec. 15 in a trade that sent Minor Leaguers Phillippe Aumont, Tyson Gillies and J.C. Ramirez to Philadelphia.

The eight-year veteran is 90-52 lifetime with a 3.97 ERA. He has struck out 900 batters and walked 332 in 1,196 innings with the Indians and Phillies. The 31-year-old won the American League Cy Young Award in 2008 with Cleveland.
