Wales and Ospreys winger George North has been handed a four-game ban following his red-card incident during the recently concluded Prop14 encounter against Dragons.
North was sent off in the 15th minute after tackling Dragons winger Ashton Hewitt in the air and despite his absence, Ospreys went on to manage a 20-20 draw in the encounter at Swansea.
The 28-year-old was proved guilty of breach in Law 9.17 that deals with 'A player must not tackle, charge, pull, push or grasp an opponent whose feet are off the ground'.
As a result, he was initially suspended for eight weeks that was reduced by half following his clean disciplinary record, guilty plea and other mitigating factors.
"It didn’t matter what I made of it," said Ospreys head coach Toby Booth.
"George is disappointed and has apologised to the team. Everyone knows he is not a malicious guy but by the letter of the law, the referee and the TMO came to a decision."
Ospreys are positioned seventh in the Conference A table of Pro14 with just two wins from 14 games and will face Cardiff Blues in the next round on Sunday.
