YORK City Knights boss James Ford has rung the changes in his back line for Sunday's Ladbrokes Challenge Cup clash against Rochdale - with another new boy named in the team.

Liam Harris has arrived on dual-registration from Hull KR and, while classed more as a half-back, will start the fourth-round tie at Bootham Crescent (3pm) at full-back in place of the crocked Ash Robson.

As predicted by The Press, veterans Jonny Presley and fit-again Tommy Saxton, along with former skipper James Haynes, are also back in the team, as is Ben Dent.

Only centre Nev Morrison and scrum-half Harry Tyson-Wilson keep their places in the back seven that stuttered in last weekend's narrow League One win over South Wales.

Harris, highly regarded in the City of Hull Academy and tipped for a Super League future, has been training with the Knights for a couple of weeks.

Said Ford: "He's a running half-back who can play full-back.

"In attack there's not much difference between the positions - you need to play a ball, organise and have a good selection of passes.

"At full-back he's looked comfortable under kicks and got the numbers right in training, which is another key element of the position. I'm excited to see him play."

Of Haynes, Presley, Saxton and Dent, only Haynes, once, has featured in the four games so far this season.

He had been expected to take up his old full-back role but will instead go into the centres, allowing Joe Batchelor to play in his preferred back-row slot in place of Brad Hey, who is ruled out with an ankle injury.

Ford explained: "Some people picked up injuries against South Wales - Ash Robson (thigh) and Brad rolled an ankle - which forced a couple of changes.

"We feel the strongest permutation is bringing James into the centre where he is solid and a good tackler, and using Liam at full-back."

Presley and Saxton, a Challenge Cup winner with Hull in 2005, had been expected to be brought back in, though the recall for Dent is more of a surprise.

The 25-year-old winger will be seeking the form that made him Championship One's top try-scorer in 2014.

Ford said: "Ben's not played for a while but he's got quality, we know that.

"He's got good skill and is a great finisher. For one or two reasons he fell down the pecking order. He wasn't overly happy about that and I didn't want him to be, but he's got the opportunity now and he's got the ability to grasp it."

Wingers Dee Foggin-Johnston (thumb) and Tommy Brierley and stand-off Danny Sowerby drop out.

In the pack, George Milton, on dual-reg with Hull KR, is unavailable, with Rovers not wanting him to be cup-tied, although Kieran Moran, on loan from the Robins, is in the 19 along with club-mate Harris.

Pat Smith remains sidelined by his ribs injury.

Knights (probable): Harris, Saxton, Haynes, Morrison, B Dent, Presley, H Tyson-Wilson, Robinson, Ellis, Dixon, E Smith, Batchelor, Spears. Subs: Carter, Moran, B Tyson-Wilson, Porter. Stand-by: Brierley, A Dent.

Rochdale (probable): Greenwood, Riley, Holmes, Gailbraith, Massam, Palfrey, Yates, Taira, Moores, Bennion, Case, Crowley, Middlehurst. Subs: Maneely, Tahraoui, Hadden, J Smith. Stand-by: Francis, Fowden.

* FORMER dual-code superstar Jason Robinson, a two-time Challenge Cup winner with Wigan, also lifting the Lance Todd Trophy as man of the match in the 1995 final victory over Leeds, will help conduct the fifth round draw, which will be broadcast live on BBC 5Live’s Breakfast Show from 7.45am on Tuesday.
