Love, who has missed the T-Wolves' last 47 games while recovering from surgery on the third and fourth metacarpal in his right hand, will now have a procedure done on his left knee.
The surgery, to be performed by Dr. David Altchek later this week, is meant to clean out a buildup of scar tissue in the knee.
Since the recovery time is 4-to-6 weeks, Love is officially out for the rest of the season.
The fifth-year veteran has played in just 18 games in 2012-13. He averaged 18.3 points and 14.0 rebounds in his limited action.
