SAINTS are almost certain to be without former skipper Jon Wilkin for Friday's clash at Warrington.

The loose forward suffered concussion in Sunday's game after trying to tackle former teammate Mark Flanagan.

He went off for a concussion assessment and never returned to the field, with the short turnaround from Sunday to Friday giving little time for recovery.

With Morgan Knowles still suspended, Saints are expected to bring in Matty Lees to spell the loose forward role with Louie McCarthy-Scarsbrook.

James Roby, who came off late in the game with a dead leg, is expected to be fit to play on Friday.

Coach Justin Holbrook said: "Jon is likely to be out. He came off but he could not go back onto the field. It is the right thing to do and we have to look after the player’s welfare.

"He was definitely concussed, but was fine at half time but we could not put him back on.

"We missed him – and with not having Morgan Knowles playing either, we lose that ball playing role at 13.

"It did affect us a bit and took a while for us to settle down.

"So it it is likely that we will make one change, Matty Lees comes into the calculation.

"He has been playing tremendously well for Sheffield in the Championship and getting through big minutes. We will need a forward there so it is likely he will get a run."
