Ulster v Leicester: Teams

Two former champions clash at Ravenhill on Friday, with Ulster and Leicester vying for a place in the last eight.

Just three points separate Ulster, Leicester and Clermont in Pool Four with two matches remaining - so there is everything to play for.

Ulster have been buoyed by the news Ian Humphreys and Pedrie Wannenburg have both been passed fit for the clash.

Humphreys (hamstring) and Wannenburg (ankle) had picked up knocks in the RaboDirect PRO12 encounter with Edinburgh at Murrayfield.

However with the duo being cleared to play, Ulster make just the one change to their line-up - with Paddy Wallace replacing the benched Ian Whitten.

Fresh

Also among the replacements, Nigel Brady is set to make his 100th appearance for the club after he was preferred to Andi Kyriacou to cover the hooker berth.

Leicester director of rugby Richard Cockerill has made just two changes for the trip to Belfast.

Both alterations come in the front row, with Marcos Ayerza and Martin Castrogiovanni handed starts.

"We've got a couple of guys back from injury and we've rotated the squad over the last few weeks so we go there fresh and ready," said Cockerill.

"We've been going well recently and that good form allows us to take some confidence in our game.

"It will be tough because Ulster are a good team and it is a very tough pool. It is a must-win game for both sides. At this stage of the Heineken Cup that is what it is all about."
