Watch: Jefferson finishes LeBron alley-oop feed with vicious dunk on Rozier

Richard Jefferson's high-flying late-career act rolls on unabated.

Having already authored a few monstrous dunks this season, the 36-year-old Cleveland Cavaliers forward added another notch to his belt Wednesday night, taking a LeBron James feed and crushing a two-handed alley-oop jam over Boston Celtics guard Terry Rozier.

As if that wasn't injurious enough, Jefferson added the insult when he hung on the rim and swung his legs around, whacking Rozier in the head with his crotch. Rozier took exception, whipping the ball at Jefferson's back and earning himself a technical foul to complete the disastrous trifecta.
