Minnesota Timberwolves guard Martell Webster underwent a surgical procedure this morning to repair a herniated disc in his back according to the Star Tribune’s Jerry Zgoda.

Zgoda reports that while there’s no timetable for his return, the typical recovery for the minimally invasive procedure called a micro-discectomy is four to six weeks.

The injury was apparently sustained during Webster’s run with the Portland Trail Blazers in last season’s playoffs, though training camp and preseason games aggravated the injury.

Though Webster was an important offseason addition, the Wolves still have a glut of wing including Michael Beasley, Corey Brewer, Wayne Ellington and rookies Wesley Johnson and Lazar Hayward.
