East Lansing – Michigan State center Matt Costello underwent successful arthroscopic surgery on his left knee on Tuesday. He will be out a couple weeks before resuming full basketball activity.

Costello, who just finished his junior season, had been bothered by the knee for the last few weeks of the season. Any time he was asked about it, however, he declined to talk about it.

After Michigan State lost to Duke in the Final Four, coach Tom Izzo indicated Costello was likely headed for surgery.

"He definitely got some cleaning up of his knee in some way shape or form," Izzo said. "It really took him back the last five, six weeks, not that anything was going to make it worse. It looks like he has some floating cartilage that is going to be cleaned up a bit. Nothing looks to be major but definitely hindered his play."

Costello averaged seven points and 5.2 rebounds a game for the Spartans. He started six games before coming off the bench for the bulk of the season while averaging 20.4 minutes a game.
