CHARLOTTE, N.C. -- The Charlotte Hornets will be without rookie guard Devonte' Graham indefinitely after an MRI revealed a condylar lesion in his right knee.

Graham will miss the remainder of the Las Vegas Summer League and will return to Charlotte for further evaluation by the Hornets medical staff.

Graham had played well for the Hornets in Las Vegas, averaging 10 points, 6 assists and just under 3 rebounds per game.

The Raleigh native was the 34th overall pick in June's NBA Draft, and the Hornets acquired his rights from the Atlanta Hawks in a draft night trade.
