Minnesota Timberwolves forward Mark Madsen had surgery on his shoulder Friday, four days after he was hurt on a personal watercraft.

Madsen was using the watercraft Monday and was hurt after he had to bail off the machine and dive into the water, a team spokesman said. Team orthopedic surgeon Dr. David Fischer and Dr. Brad Nelson performed the surgery to repair his right shoulder.

If all goes well with his rehabilitation, Madsen should return some time in November.

"This was an unfortunate accident that I have put behind me. My focus now is to concentrate on my rehabilitation with the goal of returning to the basketball court as quickly as possible," Madsen said in a statement issued by the team.
