Pro12: Ulster v Cardiff Blues (Fri) Venue: Ravenhill Date: Friday 25 October Kick-off: 19:05 Coverage: Live on BBC Two Northern Ireland and the BBC Sport website Stuart Olding makes a surprise start at full-back for Ulster in Friday's Pro12 game against Cardiff at Ravenhill. It is Olding's first game for Ulster in that position, with Jared Payne moving to outside centre and Darren Cave dropping to the bench. In the only other change to the team that won in Montpellier last week, prop Tom Court is replaced by Callum Black. Richard Smith makes his first Pro12 start for the Blues, replacing the injured wing Alex Cuthbert. Cardiff make a total of two changes to the side that defeated European champions Toulon last weekend. The other change to the starting line-up sees Dafydd Hewitt comes in at centre for Owen Williams, with Cory Allen moving to outside centre. Mike McComish, man of the match for the Ulster Ravens last week, replaces the injured Iain Henderson on the bench for the home side. Stuart Olding admitted he feared he had been dropped when his name was not called out at out-half or at centre. "When the team was read out and I wasn't playing at out half or centre, I thought that I was going to be on the bench again, but I was really pleased when I learned that I would be starting at full-back," he said. It is a position that I really enjoy playing in. I was full-back for Ireland under 20s in the Six Nations and the Junior World Championship, so I am very confident there and I am looking forward to tomorrow night's game. Cardiff's Director of Rugby Phil Davies has called on his side to build on their impressive Heineken Cup win over Toulon, but acknowledged that Ulster will also be full of confidence after defeating Montpellier last week. "We know what it is like to try and go to Montpellier and get a result so you have got to give them huge credit for that - it was a great performance by Ulster," he said. Ravenhill has been redeveloped and it will be a great atmosphere and hopefully a great game.
