Ulster will be without Shane Stewart and James Topping for their Heineken Cup fifth round tie with London Wasps at Loftus Road on Sunday (3.45 pm). But good news for the northern province as they chase a play off spot is the return to fitness of Jeremy Davidson, who took a full part in his side's game with Munster last Friday, and Bryn Cunningham who came on as a replacement in that game.

Ulster must beat London Wasps on Sunday and then account for Benetton Treviso at home the following week to see - assuming Stade Francais win their two games - if they get through as one of the best runners-up. They will announce their side later today (Wed).
