Duo's World Cup worry
Ireland World Cup hopefuls Andrew Trimble and Paddy Wallace are not expected to play again this season after picking up hand injuries in Ulster's Magners League defeat to Leinster last weekend.
Even if Brian McLaughlin's side make the league final on May 28, the Ulster pair would be unlikely to feature after they both sustained fractured thumbs, which could rule them out for at least six weeks.
It is bad timing for Wallace and Trimble, who featured in Ireland's Six Nations campaign and were looking for a strong end to the season to stay at the forefront of Declan Kidney's mind.
Leinster pair Fergus McFadden and Shane Horgan are battling hard to make the plane to New Zealand and can continue to impress Kidney as the province chases glory on two fronts.
Ulster face Connacht in the league at Ravenhill on Friday night and must also do without BJ Botha, who has been ruled out for the rest of the season with a knee injury. The tight-head was due to have an MRI scan yesterday to determine the extent the damage.
Tom Court is also expected to miss the Connacht match with concussion but Johann Muller and Simon Danielli are set to return. Muller will partner Dan Tuohy in the second row with Danielli set to replace Trimble on the right wing.
Jerry Cronin is set to get his first start of the season after impressing at tight-head in the absence of the injured Declan Fitzpatrick.
