Tom Daley had been due to make his first competitive appearance on Friday in the 10m synchro platform, but missed out after his partner Blake Aldridge's suffered a broken nose after he was involved in an alleged nightclub fracas in Southampton last Friday.
The match had enjoyed a stormy build-up, the Dragons' dramatic fightback for a 33-35 win in Treviso last week having been followed by the Welsh side's players Rhodri Gomer-Davies and Thomas breaking a curfew and getting arrested following a nightclub fracas.
