Andre Roberson will be out at least three weeks with a right knee sprain.

Roberson suffered the injury in Sunday's loss by the Oklahoma City Thunder against the Brooklyn Nets.

Russell Westbrook crashed into Roberson's right leg after flying in for a missed reverse layup.

Roberson limped to the bench and eventually the locker room, not returning. He was seen postgame without crutches, but walking with a heavy limp.
