Blades has named five forwards on the bench for the match as he anticipates the physical nature of the Exiles side.
Hookers Dave Wilson and Nick Makin, prop Marius Hurter and loose forwards Jon Dunbar and Phil Dowson have all been named on the bench.
"We need to perform well up front to give us a platform to play the way we want to play. We've trained well this week and the team are certainly looking forward to the match," said Blades.
