With the departure of Kevin Maggs and David Humphreys to the Ireland squad, Ulster coach Mark McCall has been forced to make changes to his side for their match against Munster on Saturday at Ravenhill.

Irish coach Eddie O’Sullivan has cut down his squad for the game against South Africa to a final 22, and in the process has released the other players to play with the provinces at the weekend.

Ulster today confirmed that they have signed former Harlequins flanker Tu Tamarua. Tamarua, who represented Australia at schoolboy level, has played for clubs in England, Wales and New Zealand. He could make his debut as early as Saturday against Munster at Ravenhill.

Eddie O’Sullivan today finalise his squad for the autumn internationals against South Africa, USA and Argentina. When the preliminary squad was announced last week, 5 vacancies were left.
