Webster replaces injured Leonelli

Webster, who scored the winning try in the 32-31 win over London Wasps in the Gunners' last home match in this competition, will replace Argentinean international Francisco Leonelli who has been forced out with a groin strain. Canadian international Michael Pyke will replace Webster on the bench.

Edinburgh Gunners' interim head coach Todd Blackadder said: "Francisco's injury is nothing too serious but we've decided to bring Simon Webster into the starting line. He is on fire at the moment so I don't feel we've lost anything with the switch. It also gives Mike Pyke a chance to play in his first Heineken Cup game."
