Ulster full-back Will Addison has been suspended for four weeks for a tackle on Clermont Auvergne's Paul Jedrasiak during last weekend's Heineken Champions Cup win for the province.

Shortly before the half-hour mark of the 18-13 win at Kingspan Stadium, Addison attempted to tackle the Clermont lock but the players clashed heads.

Referee JP Doyle consulted with the TMO at the time and decided no punishment was necessary but Addison was cited in the aftermath and was found guilty of "reckless contact with Jedrasiak's head in attempting the tackle" by an independent disciplinary hearing in London today.

The standard punishment for a mid-range dangerous tackle is six weeks but that was reduced to four given the four-cap Ireland international's previous good record. 

Unless an appeal is forthcoming, Addison will be free to play again on Monday 23 December, which means he will miss the Pro14 games against Scarlets and Leinster and the Champions Cup double-header against Harlequins.
