Ratchford missed the World Club Series clash with St George-Illawarra last week with a shoulder injury he sustained in the win over Hull FC.
While he looks unlikely to play against Catalans Dragons this Saturday, he is set to return to action next weekend.
“Hopefully I will be back next week. We have got a tough game against Hull KR,” he told Sky Sports News.
“I am hoping to start running towards the end of the week and see how we go from there.”
Ratchford is also not anticipating too much of a hangover from their World Club Series defeat for the Wolves.
“I don’t think it (the World Club Series defeat) is going to affect us too much,” he said.
“We are a pretty confident group and it kind of shows in the way we play. We are pretty confident in how we are and the way we play.
“We were disappointed to come away with a loss but we have taken a lot of confidence out of the game and we had a lot of opportunities to score points ourselves and didn’t quite do that, so it’s not going to affect us too much.
“The last couple of years we have had a pretty good record against Catalans so we are confident going over there.
“They have had a bit of an up-and-down start and it has been a pretty good hunting ground for us these past couple of seasons.”
