Leeds Rhinos coach Richard Agar optimistic over the extent of Ava Seumanufagai’s injury

Seumanufagai limped off after damaging a knee early in Wigan forward Liam Farrell’s testimonial game and did not return.

“We think, at the moment, it’s a low-grade medial injury,” Agar said. “We will have to see how that settles down over the next 24-48 hours.

“If it is low-grade, touch wood he will be good to go for two weeks, but it is too early to make an accurate assessment at this stage.”

Agar said Brad Dwyer “hurt his back and it started tightening up a bit”, but the hooker is not believed to be a concern for the Hull game.

Prop Matt Prior, and loose-forward Cameron Smith missed yesterday’s game due to a sickness bug which has also affected hooker Corey Johnson.

Rhinos trailed 10-0 early in the second quarter, but a try on the stroke of half-time got them back into the contest and they dominated the final 40 minutes.

Leeds went ahead through a penalty goal with 12 minutes left and scored two late tries to seal their third successive pre-season win.

Wigan had earlier tapped a kickable penalty and Agar insisted: “I didn’t issue that order to kick for goal!

“It tells you something about the players, they are saying it is a trial game, but we want to win.”

Agar stressed: “The result wasn’t that important to me.

“If it had been a 10-10 draw that wouldn’t have worried me and if we’d lost 12-10 it wouldn’t have worried me too much.

“It was more about the performance and for us as a team learning some big-picture stuff.”

Of Leeds’ display, he said: “We committed some unforced errors coming out of our own end and we squandered a couple of chances in the first 10-15 minutes when our ball movement was really positive.

“We then spent a huge chunk of the game defending and there’s a couple of little bits to learn off the way we conceded tries too.

“But I was happy we came off the ropes for 10-6 at half-time after we’d had an enormous amount of consistent pressure against us.”

Agar said he had deliberately made only limited interchanges in the opening period.

“We wanted to really put our guys under the pump against a strong Wigan team,” he said.

“We wanted to push them out under a bit of fatigue and see how we coped under pressure. To go in at 10-6 after being under so much pressure showed a fair bit of resilience from our boys.”

Agar added: “In the second half we fixed up some of the ball control issues and just played a bit of rugby really. “There were good performances from some of our younger kids and from some of our most established players too.”

Agar felt full-back Jack Walker was Leeds’ best player and also praised teenage prop Thomas Holroyd on his return after a long spell on the casualty list.

“We was a real bright spot for me,” he said of Holroyd. “He’s a big, strong boy, he carries the ball well and he’s aggressive.”
