Three new faces for Ulster's bid for European glory against Wasps
Cave, Treadwell and McCall come into side which beat La Rochelle
Ulster have made three changes to the side which beat La Rochelle last weekend for Sunday’s crunch European tie away to Wasps.
Darren Cave (pictured), Kieran Treadwell and Kyle McCall all come in.
And 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.
Team as follows: (15-9): C Piutau; L Ludik, D Cave, S McCloskey, J Stockdale; C Lealiifano, J Cooney;
(1-8): 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.
