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.
With the memories of last season's final day drama still firmly in the memory, supporters can sign-up for the next chapter of the Worcester Warriors journey as Season Tickets for the 2015/16 campaign will be available on Wednesday 1 July.
