I'm struggling to see Sirker being given an extension if he can't even get a game for Coventry at the moment (unless anyone else has any further insight as to why that may be)
After scoring a hat trick in the Wasps A vs L. Irish A match on 18th April Sirker didn't make any further appearances for Cov leading to speculation that he'd been recalled from his loan period by Wasps. His recent appearance as a travelling reserve at last Saturday's match against Wuss would suggest that there could be some truth to this theory?
