Report: J.R. Smith won't be disciplined for flagrant foul on Horford

The NBA won't issue additional discipline to Cleveland Cavaliers shooting guard J.R. Smith for his late-game flagrant foul against Boston Celtics All-Star Al Horford, league sources told ESPN's Adrian Wojnarowski.

With less than four minutes remaining in regulation and the Cavaliers trailing by eight, Smith shoved an airborne Horford in the back as he attempted to catch an alley-oop, sending the Celtics center tumbling. Smith was assessed a flagrant 1 for the infraction, remaining in the game but being subjected to a cascade of boos and four-letter chants from the crowd in Boston.

He admitted to overstepping the boundaries of acceptable play after the game, telling reporters: "It was a good call; I blatantly pushed him."

The Cavaliers have lost Games 1 and 2 of the Eastern Conference finals by a combined 38 points. In his time on the floor in the series, Smith has been miserable, averaging two points, two rebounds, and one assist per game while shooting 12.5 percent from the field, and posting a minus-23 in 56 total minutes.
