"To play against the Pumas well you first do the hard work and that's where we suffered on the weekend - around the tackle," said Blades.
On the plus side for the tourists, hooker Tatafu Polota-Nau and Radike Samo are confident they will overcome shoulder problems to play.
Of the five players carrying injuries, it appears winger Digby Ioane (knee) and Scott Higginbotham (back) are in most doubt. Centre Anthony Faingaa has been cleared of a head knock and is expected to replace Adam Ashley-Cooper in the midfield.
