Watch: Crowder gets away with leg-locking Lopez under the hoop

The Celtics had a tough time containing Robin Lopez on Wednesday night, but Jae Crowder finally seemed to stumble onto something in the fourth quarter, when he took a page out of Matthew Dellavedova's book.

After Lopez emphatically denied him at the rim, Crowder hit the floor and leg-locked the Bulls center, rooting him in place and somehow evading the referees' whistle as the Celtics recovered the loose ball. Crowder let go just in time for Lopez to pick up a foul on Al Horford at the rim.

Lopez was, understandably, less than impressed.
