Good afternoon and welcome to this Challenge Cup pool 5 fixture as Harlequins host Edinburgh at The Stoop. Both sides have won 3 of their last 4 European games and today's clash is crucial in deciding who tops the pool. Stay with us for live updates throughout.

Edinburgh need their best performance of the season by some way if they are to win this one. If they do a home QF is a distinct possibility. If they don't qualification looks fairly unlikely. Make or break time. Come on Edinburgh!
