It was deffo forward and there were a few other mistakes not picked up that on balance probably wouldn't have saved Widnes but would have kept the nuetral happier..
..dixon catching from in field and landing behind the try line not given as a dropout, HUBY & about 2 other Cas forwards infringing the 10metres (AFTER Bentham had told them to keep the 10) which meant that the Widnes winger looked up at them and missed the ball Cas then scored sstraight on the next possesion (similar was given as a penalty when Australia scored against us when Tomkins dropped it in the 4 nations)
Cas were easy winners without them though
