Connacht head coach Eric Elwood has made just one change to his side for their Heineken Cup trip to Biarritz on Friday (Live on RTÉ Radio 1, 8pm).
Elwood's men claimed a hugely impressive victory over the Basque side last weekend at the Sportsground and he has made minimal changes to his side for the return leg.
Johnny O'Connor replaces Willie Faloon in the back row where he is joined by Andrew Browne and Eoin McKeon.
Faloon was ruled out of selection earlier this week due to a fractured eye socket he incurred in last Friday's 22-14 victory.
Nineteen-year-old Robbie Henshaw, who just signed a new contract with Connacht, will again line out at full-back, while Dan Parks whose kicking was instrumental in last week's victory, will captain the Westerners.
On the bench, forwards Nathan White and George Naoupu make a welcome return to the squad having both missed out on last week's round three clash.
Biarritz will have their captain Imanol Harinordiquy back in the pack.
The France international back row started on the bench for last week's defeat, while fellow international Damien Traille also returns for the Basque side.
There will be full live coverage of Biarritz v Connacht on a specially extended Sport at Seven on RTÉ Radio 1 on Friday 14 December from 7pm.
