Ireland prop Jack McGrath to leave Leinster for Ulster

McGrath, who is contracted to the Irish Rugby Football Union, has won 57 caps but has slipped behind provincial colleague Cian Healy in the loosehead pecking order.

"This was a difficult decision but one I believe will put me in the best position to continue to perform at the top end of the game," McGrath said.

"I have enjoyed a huge amount of success at Leinster but I feel that looking beyond the World Cup to the next phase of my career I will benefit from the opportunity within the Ulster environment."
