Ireland internationals Andrew Trimble, Stephen Ferris and Tommy Bowe are set to return to the Ulster side for their Heineken Cup trip to London Irish.

Trimble and Bowe missed the drawn Celtic League encounter with Leinster due to injury while Ferris, who was rested at the weekend, is expected to come back into the side with Kieron Dawson making way.

"We will be selecting from a full deck," McCall told BBC Sport. "Both Andrew and Tommy will be playing at Reading. Thankfully there were no problems after Saturday's game."

The exiles, meanwhile, will be without French flanker Olivier Magne after he was given a two-week suspension
for stamping on Northampton's Dylan Hartley.

The ban dates back to November 29th when Magne was suspended by his club - and means he will be available for the return game at Ravenhill on December 15th.
