Worcester's injury problems have deepened with Leonardo Senatore and Dean Hammond joining the casualty list.
Argentina back-row Senatore had about as bad a day at the office as it possible to have in union - he was sin-binned within a minute of coming on as a replacement in the defeat to Harlequins, and when he came back on he
dislocated his shoulder.
South African winger Hammond has torn his hamstring.
Coach Dean Ryan told the Worcester News: "We lost a couple of players on Saturday. Leonardo went off with a dislocated shoulder and Dean played the last 10 minutes with a torn hamstring.
"That was up against one of the fastest back threes I've ever seen, so we're hurting a little bit.
"The boys have got a bit of time off this week - it's the right time to get away and then we'll throw everything at Wasps back at Sixways and see if we can get something."
