England second-row Shaw underwent a scan yesterday aftersustaining what was thought to be a rib injury during last weekend's Premiershipmatch against Leeds Tykes.
Shaw started the Headingley match on the bench but came on midwaythrough the second half to help English champions Wasps to a hard-fought 11-7victory.
However, Shaw (30) appeared to be the victim of a stampingincident although there was confusion as to whether he had suffered from foulplay after a touch judge raised his flag only to change his mind.
Although it was first thought Shaw was suffering only from bruisedribs there were fears that the pain he suffered up until the final whistlewas indicative of spleen damage.
But his scan erased those fears and Wasps coach Warren Gatlandsaid having the 6ft 9ins Shaw in the pack would be a huge boost to his side asthey chased their first European Cup title. "Losing Simon would have been a huge blow for us so we'redelighted that he's been given the all-clear. He's a crucial part of the team,"said Gatland.

Under tournament rules, the semi-finals are played at a 'neutral'venue in the country of one of the competing clubs. In practice this means Wasps will arrive at a packed LansdowneRoad with some 45,000 home fans roaring Munster on with only some, 2,500supporters of the London club crossing the Irish Sea.
But London Wasps, led by England captain Lawrence Dallaglio, are wellused to hostile environments - in their final Pool match they travelled toFrench club Perpignan in February and won 36-4.
"We were delighted when we beat Gloucester in thequarter-finals because playing at a packed Landsdowne Road where most of the fans will besupporting Munster is something we'll relish," said New Zealander Gatland.
"It was a daunting task going to Perpignan but we camethrough that well. There is no trepidation among the players over the task facing us onSunday - it's a massive challenge and the team will respond to it.
"If we play to our potential then we can beat Munster andthat's what we're setting out to do.
"They are the heart and soul of the Ireland side, so we'refamiliar with them. We know their strengths and weaknesses and will look to exploitthem."
