GLASGOW Warriors were dealt a huge blow today when Moray Low was ruled out for eight weeks after suffering damage to the medial collateral ligament on a knee.

The tighthead prop will miss Glasgow's forthcoming Heineken Cup games and the start of the RBS 6 Nations Championship.

Coach Sean Lineen said: "This is disappointing news for Moray."

Stand-off Ruaridh Jackson's hamstring injury is not as bad as first feared and he will continue to be monitored by medical staff.

Meanwhile, Colin Shaw said the Warriors have learned lessons from their first Heineken Cup meeting with European champions Leinster.

That was in November, when a first-half blitz all but ended the Pool Three encounter as a contest before the break, the Irish outfit ending up 38-13 winners.

However, with Sean Lineen's side facing the return leg at Firhill on Sunday, Shaw claims Glasgow will not be caught cold a second time.

The Warriors wing said: "Leinster took us apart at the contact at the Royal Dublin Showgrounds. They got quick ball off the back of pretty much every ruck, and we are going to have to knuckle down there.

"We are going to have to give them a real hard ride at the contact and, defensively, step up to the plate.

"I think that day it wasn't so much we were bad, just that they are the European champions and played like champions."

The 28-year-old, who has been with Warriors for six years, is engaged in a selection battle with summer signing Tommy Seymour, though the former Hawks star's greater defensive awareness perhaps gives him a slight advantage.

Shaw added: "If selected, this would be the most important game I have played in for Warriors. There is just so much riding on it."

Off the field, back-row star James Eddie has signed a new two-year deal.

The 26-year-old said: "I'm thrilled to have been given the opportunity to play a full role in the Warriors squad over the coming two campaigns."

Warriors' season-ticket holders can bring a friend or family member to the match for free.
