Danny Craven was Featherstone’s only minor casualty in Friday’s 28-16 win against Sheffield.
Stand-off Craven was taken off late in the game with a calf injury and faces a fitness test before Monday’s trip to London Broncos.
“We will make a late call on Craven. Apart from him we are fine,” said Rovers coach Jon Sharp.
“He has a tight calf. It was gripping and we erred on the side of caution.”
Rovers will aim to repeat their Challenge Cup fourth round win at London when they visit West Ealing for the second time in 10 days.
“We go there in good spirit and good heart and with lots of confidence,” added Sharp.
“When you win the first game of the Easter period you can’t underestimate the positivity it brings.
“When you are winning it creates momentum and you want to keep playng and we are now looking forward to London.
“We are going to try to do things a little bit differently this time around. We were good last time but I think we are just going to mix it up a bit and try to freshen the team up and give other blokes opportunities.
“I was really pleased with Sam Day and Luke Cooper when we played against London in the cup. Those guys will probably come back into the mix because they were excellent against them last time.”
