Munster have revealed that back row forward Denis Leamy will be out of action for up to four months due to a hip injury.

Leamy, who has won the Heineken Cup twice, in 2006 and 2008 with the Irish province, will undergo surgery to rectify the niggling hip injury - ruling him out of his side's remaining European pool games.

"Denis will be out probably for four months. He will have an operation, and is getting it finalised," said Munster head coach Tony McGahan.

The 30-year-old has played in all four of Munster's clashes in the competition this season but will miss the final two games against Castres Olympique and Northampton Saints.

* Meanwhile Glasgow Warriors duo Ruaridh Jackson and Moray Low face a race against time to be fit for their side's tie at home to Champions Leinster the weekend.

Flyhalf Jackson and prop Low both left the field in the first half of the Warriors' defeat to the Scarlets last Saturday.

Jackson limped off at Parc y Scarlets with a hamstring injury, while Low departed with a knee injury.

Both players will be further assessed this week to find the full extent of their injuries but it could be a big blow to the Warriors as the top two in Pool Three go head-to-head.

Glasgow sit in second, six points behind the reigning Heineken Cup Champions with two rounds of action remaining.
