Perry, who was fined by police for running naked down a street in St Helens after going last season try less, bagged a brace of tries in the 48-18 victory, but then added to Nathan Brown’s injury woes late in the game.
Brown said: “We are not sure to the extent of it but the initial reports aren’t good.
“He got two nice tries. Hopefully it is not as bad as they are thinking at the moment.”
The former Huddersfield coach has seen his new side dogged with injuries since the start of the year, although they still sit fourth in the table.
He added: “I am sure it will turn around. Hopefully things will change and we can get some stability. You just feel for the players because they all want to play and do well.
“We are just in a phase where things aren’t falling our way in that area.”
