Chris Czekaj returns to the Cardiff Blues line-up for their must-win Magners League clash against Connacht on Friday.
The full-back was forced out of the Blues' draw with Ospreys a fortnight ago by a knee injury but is raring to go ahead of the trip to Connacht.
In the second change to the Cardiff starting XV, Welsh international John Yapp has recovered from a calf injury to take his place at loosehead prop.
Connacht have named an unchanged starting line-up from the team that beat Edinburgh two weeks ago.
With Michael Swift still out with a hand injury, Bernie Upton continues his partnership with Mike McCarthy in the second row.
Form: Connacht have won three of their last four games in the Magners League, whilst of late at the Sportsground their form has been impressive with five straight victories - their best ever league run.
Cardiff Blues have secured just one victory from their last four outings: 16-11 at Edinburgh on 4 March. The Blues' only away Magners League defeat since December was 12-32 against Ulster at Ravenhill on 25 February.
Connacht's only win over the Blues in their last ten encounters was 18-16 at the Sportsground on 18 September 2009.
