Ulster Head Coach, Mark Anscombe, has named an extended 27-man squad for Friday night's crucial RaboDirect PRO12 game against Cardiff Blues at Ravenhill (kick off 7.45pm).
If Ulster win the match, they will finish the season top of the RaboDirect PRO12, therefore guaranteeing a home play-off at Ravenhill.
The match will be particularly significant for both Chris Henry and Robbie Diack. Both players are set to make their 100th appearance for the Province.
Back Row forward, Sean Doyle, is included in an Ulster Squad for the first time since breaking his leg in a club game in October.
There are no tickets for the fixture remaining. The match will be the 10th sold out game at Ravenhill this season.
