Quins, who were knocked out of the Powergen Cup last weekend by Leeds, are expecting a tough encounter against Bath and are not reading too much into the club's massive injury-count, which recently saw them lose new signing Robbie Fleck (broken leg) shortly after his arrival.
"Bath are playing very well this season, and we are expecting a hugely physical contest at the Rec on Saturday." said Quins CEO Mark Evans.
"Bath have started the season very well, and from the videos that we have watched they deserve to be top of the Zurich Premiership. Even with the injuries they have, their squad is very strong, and it is clear that everyone within the squad understands their role and carries it out well."
