WATCH: Fans tear into referee over awarding Ulster penalty try for Rob Kearney foul

Ulster’s 30-6 Guinness Pro12 victory against Leinster on Saturday wasn’t without its controversy.

18 minutes into the clash, Leinster conceded a penalty try and Rob Kearney was sent to the sin bin for his foul on Ruan Pienaar.

Ulster were on the attack when Pienaar chipped a kick deep into the Blues’ 22 and chased after it in pursuit of a try. Kearney appeared to make no effort to get out of the scrum-half’s way and proceeded to take him out off the ball, causing the South African to go crashing down to the ground in a heap.

Referee George Clancy went to the TMO, then showed Kearney the yellow card and awarded a contentious penalty try to the Northern province.

While everyone was unanimous in agreement that Kearney deserved a yellow card for the foul, very few could understand why the referee decided to award Ulster the penalty try when Kearney wasn’t the last man, and also it looked as if Pienaar was never going to win the footrace to touch down a try.

Not sure about the penalty try decision. Would have to be a try without any reasonable doubt. McGrath was running for it also. #ULSvLEIN
