Jerome Gout is definitely out for Toulouse after recently needing a wrist operation.
Former Leeds forward Simon Worrall (shoulder) is still being assessed as Toulouse aim for three points that could push them into the play-off places.
However, coach Gilles Dumas knows his team need to improve from their recent 38-24 defeat at Sheffield.
He said: “I didn’t see the same team playing at Sheffield as I had at Widnes and Featherstone. There were too many mistakes and too many missed tackles.”
Featherstone are aiming to take revenge against Toulouse, who less than a fortnight ago became the first team to defeat Rovers in the Co-operative Championship when they won 26-24 at Bigfellas Stadium.
Powell said: “The forward challenge is going be tough and the challenge in the heat is going to be big, but I think we’ve got a tough group this year and if anyone can do it I think it’s us.”
