St Helens Full Back Jonny Lomax could return to make his first appearance in a year after coming a reserve game at the weekend
The 25-year-old, who was included in England coach Steve McNamara's training squad last year, missed the second half of the 2014 season with knee damage that required major surgery and he suffered a similar injury at Wakefield last March.
"If Jonny's fit, then Jonny's plays, it's as simple as that.
"He's too good a player not to have in your side. But there's of boxes to tick, before we name a side, but I'm as confident as anyone that Jonny Lomax is going to be fit."
Keiron Cunningham also revealed that Jo Greenwood who also featured in the reserve game should be fit enough to play against Leeds on Friday
