Ulster captain, Rory Best, will make his 50th European appearance for Ulster, against reigning champions Toulon, at Kingspan Stadium tomorrow afternoon (kick off 1pm).
Best, who is 32, made his European debut, against Gloucester in January 2005 in a 14-12 home win.
Tomorrow will be the first time that Ulster have played Toulon, European Champions for the past two years.
Ulster Head Coach, Neil Doak, has made two changes to the starting team that lost to Leicester Tigers at Welford Road for the match.
Stuart Olding starts the game at inside-centre, with Stuart McCloskey dropping out of the squad.
In the pack, Nick Williams moves to the bench, with Roger Wilson picked at Number 8.
The rest of the team is unchanged with Louis Ludik at fullback, Tommy Bowe on the right wing, Jared Payne at outside centre, Craig Gilroy on the left wing, Paddy Jackson at outhalf and Paul Marshall at scrumhalf.
Andrew Warwick is selected at loosehead beside Best with Wiehahn Herbst continuing at tighthead. Franco van der Merwe and Lewis Stevenson continue their partnership in the second row, while Chris Henry and Robbie Diack start either side of Wilson in the back row.
There is one other change on the bench with Ian Humphreys included in the match-day panel. Rob Herring, Callum Black, Declan Fitzpatrick, Clive Ross, Nick Williams, Michael Heaney and Darren Cave complete the squad.
