Rookie guard Xavier Henry of the Memphis Grizzlies will be sidelined for at least the next four weeks as he continues rehabilitating a right knee sprain.
The team said Wednesday he will be re-evaluated after that time.
Henry has missed 12 games this season, including the last four, because of knee soreness.
The first-round pick in last year's draft is averaging 4.3 points and 1.0 rebound in 13.9 minutes in 38 games. He's had 16 starts.
