The Ulster team has been named for Sunday’s vital Champions Cup clash against Wasps in Coventry.
There have made three changes and two positional switches to the side that got a 20-13 win against La Rochelle last weekend.
Darren Cave, Kieran Treadwell and Kyle McCall are the three new faces included by the Ulster coaching team.
With Craig Gilroy ruled out after fracturing his cheekbone against the French, Cave is selected at outside centre, with Louis Ludik moving to occupy the right wing berth.
Christian Lealiifano has been named at flyhalf for what will be his final game before returning to play Super Rugby for the Brumbies. John Cooney, Stuart McCloskey, Jacob Stockdale and Charles Piutau will complete the backline.
Treadwell’s inclusion at lock alongside Alan O’Connor results in Iain Henderson moving to the back row next to Sean Reidy and Nick Timoney. Rory Best will be flanked by McCall and Rodney Ah You in the front row.
Wiehahn Herbst has recovered from a calf injury sustained against Leinster earlier this month and is named among the replacements.
Rob Herring, Andy Warwick, Matty Rea and Chris Henry are the other forwards in the squad.
Rob Lyttle, who scored two tries for Ulster A in a bonus-point win over Cornish Pirates last weekend, has earned a place on the bench alongside Dave Shanahan and Johnny McPhillips.
A bonus-point victory would confirm Ulster as group winners, regardless of La Rochelle’s result against bottom side Harlequins, while a win of any nature would see Ulster progress as one of the best runners-up.
Ulster team to play Wasps on Sunday 21st January, 3.15pm:
C Piutau; L Ludik, D Cave, S McCloskey, J Stockdale; C Lealiifano, J Cooney; K McCall, R Best (captain), R Ah You, A O’Connor, K Treadwell, I Henderson, S Reidy, N Timoney
Replacements (16-23): R Herring, A Warwick, W Herbst, M Rea, C Henry, D Shanahan, J McPhillips, R Lyttle.
