HOUSTON - Minnesota All-Star Jimmy Butler "underwent successful meniscus" surgery on his right knee Sunday morning, according to the Timberwolves Public Relations.

After grabbing a rebound late in the third quarter Friday - in a game against the Houston Rockets - Butler pivoted and planted hard on his right foot before collapsing and grabbing his right knee. He was on the floor for at least three minutes before he was carried off the court by two teammates. He appeared to avoid putting weight on his right leg when heading to the locker room.

On Sunday, Timberwolves PR sent out a news release that read, "The Minnesota Timberwolves today announced that forward Jimmy Butler underwent successful meniscus surgery this morning on his right knee. The operation was performed by Team Orthopedic Surgeon Dr. Diane Dahm at Mayo Clinic in Rochester, Minnesota. Butler will be sidelined indefinitely and further updates as to his progress will be issued over the course of the rehabilitation process."

On Saturday, Butler got an MRI at the Mayo Clinic where it was revealed his knee had a meniscal injury.

Butler leads the Timberwolves with 22.4 points and 1.9 steals per game, adding 5.5 rebounds and 5.0 assists per game in his first season with Minnesota after being traded from Chicago in the offseason.

Timberwolves coach Tom Thibodeau said after the game - a 120-102 Houston victory - that Butler would have an MRI on Saturday after x-rays at the arena were inconclusive.
