The Memphis Grizzlies announced today that rookie guard Mike Conley will be out indefinitely due to a posterior labral tear in his right shoulder.

Conley, the fourth overall pick in the 2007 NBA Draft, originally suffered the injury on Nov. 17 against the Dallas Mavericks at the American Airlines Center. The 6-1, 180-pound playmaker will undergo rehabilitation and will miss a minimum of two-to-three weeks. He was placed on the inactive list prior to last night’s 125-108 victory over Seattle at FedExForum.

The 20-year-old is averaging 5.6 points and leads all rookies with 4.2 assists in 14.4 minutes in five games played.
