Warriors staged a full-blooded fightback to claim a bonus point in Clermont.
Warriors' final two ERC Challenge Cup matches have been confirmed as the team moves into final preparations for Saturday's clash with Albi at Sixways, the third of six Pool 5 encounters.
As expected, the home clash with ASM Clermont Auvergne will take place on Saturday, January 13, with a customary 3pm kick-off.
Warriors picked up a late losing bonus point after a hard match in the hostile atmosphere of Parc des Sports Marcel Michelin in October.
A week after meeting the French side, the group stages will conclude with a visit to Stadio Luigi Zaffanella for the return match against Viadana, which is also a 3pm kick-off (local time).
Warriors defeated their Italian opponents 25-7 in the opening round of the cup, at the start of October, following a 35-15 victory in a pre-season friendly.
Not only are the great and the good of the Aviva Premiership Rugby strutting their stuff at Twickenham this Saturday - so are the new generation of rugby players, including Worcester RFC, courtesy of the Land Rover Premiership Rugby Cup.
Warrior Stuart Brooks will represent the club at Twickenham next weekend as he battles for the honour of carrying the coveted Aviva Premiership Rugby trophy onto the pitch ahead of the final between Leicester Tigers and Northampton Saints.
