Big three back for Wasps

England trio Lawrence Dallaglio, Josh Lewsey and Joe Worsley all return for London Wasps' top-of-the-table Premiership clash with Northampton at High Wycombe on Sunday.

Fellow internationals Simon Shaw and Will Green also start in the pack after coming off the bench during last week's victory against Rotherham, while Tom Voyce is preferred to Kenny Logan on the left wing.

Wasps boss Warren Gatland said: "We can now settle down with a full squad and work towards our end-of-season goals. A win in this game is vital in order to secure a top-three finish and a place in the title play-offs."

Ambitions to play in next season's Heineken Cup will ensure a fierce encounter between London Irish and Harlequins at the Madejski Stadium on Sunday. Both clubs are caught up in the middle-of-the-table dogfight for places in Europe. The fourth and fifth-placed clubs in the Premiership qualify outright, while sixth and seventh will compete in the wildcard play-off for the final position.

Quins can also still qualify by winning the Parker Pen Cup but their two-legged semi-final against Connacht over the next fortnight will be at the back of their minds on Sunday. Pat Sanderson, Simon Miall and Jon Dawson return to the pack, Will Greenwood and George Harder come in to boost the backs, and fly-half Paul Burke hopes to pass a fitness test tomorrow.

Irish, meanwhile, welcome back centre Geoff Appleford from England Sevens duty and have Naka Drotske fit to start at hooker.
