Kieran Marmion will gain his first cap for Connacht at scrum half. Kieran started in the preseason friendly against Harlequins and also played a pivotal role for Ireland at the IRB Junior World Championship, starting four of their five games en route to a highest ever finish of fifth.
Another regular from last season is out half Miah Nikora who got a good run out in both pre-season friendlies in August.
Connacht have plenty of experience amongst the starting forwards. John Muldoon, Mike McCarthy, and Johnny O'Connor have almost 450 caps between them while Michael Swift holds the record with this his 220th cap for the Province. Ronan Loughney, with 105 caps, provides plenty more experience with George Naoupu , Denis Buckley and Ethienne Reynecke completing the firepower of the forwards.
In the past two seasons both Connacht and Cardiff Blues have begun with an opening weekend victory and tomorrow both sides will endeavour to hold on to that record.
It's been a summer of change for Cardiff Blues with a number of senior players such as Martyn Williams, Xavier Rush and Deiniol Jones retiring from the game and a new exciting crop of youngsters coming through.
Director of Rugby, Eric Elwood, is looking forward to kicking off with the new season. "All the pre-season training has led to this point and we can't wait to get going."
KO is at 5pm at the Sportsground.
