Charlotte Bobcats guard Gerald Henderson is undergoing surgery to repair a torn labrum in his left hip, a procedure that's expected to alleviate chronic knee pain.

The Bobcats announced Henderson was having the surgery Tuesday in Colorado, where a specialist discovered the injury while examining his left knee.

Recovery is expected to take 4-6 months. If there's no lockout, the Bobcats will open training camp in less than five months.

The 12th pick in the 2009 draft, the Duke product played little until coach Paul Silas replaced Larry Brown in December. Henderson was made a starter after Gerald Wallace was traded to Portland in February.

Henderson scored in double figures in 22 of the final 28 games, including a 32-point outing against Orlando.

CHARLOTTE, N.C. (AP) — Charlotte Bobcats guard Gerald Henderson is expected to undergo surgery to repair a torn labrum in his left hip.

Team spokesman B.J. Evans said Tuesday the injury was discovered by a specialist in Colorado who was examining Henderson's left knee. Henderson was plagued by knee pain for much of last season.

The recovery time following surgery wasn't immediately known.

The 12th pick in the 2009 draft out of Duke, Henderson struggled for playing time under former coach Larry Brown. But Henderson was put in the rotation when Paul Silas replaced Brown in December and made a starter after Gerald Wallace was traded to Portland in February.

Henderson scored in double figures in 22 of the final 28 games, including a 32-point outing against Orlando.
