Munster coach Tony McGahan confirmed today that Rua Tipoki has suffered some minor setbacks in his bid to return to full fitness. As a result he is definitely ruled out of next week's Heineken Cup quarter final clash against the Ospreys. McGahan said this afternoon he cannot look any further than the next two weeks before giving an assessment of the Kiwi's return to playing. Munster welcome all of their Irish Grand Slam winning contingent back to the squad for a top of the table clash with Leinster at Thomond Park this Saturday in the Magners League.
