TORONTO coach Paul Rowley is looking forward to seeing how his undefeated players respond to being the underdogs when they take on Super League high-flyers Salford tomorrow.

The newly-formed Canadian team face comfortably the biggest test of their brief existence when they take a break from their promotion campaign in Kingstone Press League 1 by continuing on the Wembley trail.

The Wolfpack knocked out London Broncos in the last round and have won all five league matches so far, piling up 162 points in their last two alone while conceding just six.

But they will get a more accurate gauge of their potential when they take on a rejuvenated Red Devils side in the fifth round of the Ladbrokes Challenge Cup at the AJ Bell Stadium.

"We're huge underdogs so that's something new to us, it's refreshing," said Rowley, who is set to give a debut to the club's latest high-profile signing, Scotland half-back Ryan Brierley.

"Salford are riding high at the top of Super League but it's a good time to play them, you want a big club early and we're looking forward to it.

"Obviously playing a team like Salford is good for us and the outcome doesn't damage us in terms of our objectives for this year. I guess it will be interesting to tell us where we're at as a team.

"We set our targets and our levels quite high and it's quite easy to drop off when you are beating our opponents like we have done in the last two weeks.

"It will be a stark reminder of the intensity required. That will be the biggest challenge, competing in an arm wrestle for long periods of time which we've not had to do yet."

Championship leaders Hull KR will also get the chance to test themselves against top-flight opposition when they go to Leigh on Saturday.

It will be the Robins' first competitive fixture against a Super League club since defeat to Salford in the £1million match condemned them to relegation in October, but coach Tim Sheens is downplaying its significance.

Although Sheens' men will have to overcome top-flight opponents in the Super 8s Qualifiers if they are to secure a return to Super League in 2018, the veteran Australian does not believe the match will have any bearing on results towards the end of the season.

"If it was their strongest side and our strongest side, with both teams being fresh, then it might be more of indicator but I don't think that's the case this week," he said.

"It's more about who can last the full 80 minutes and hang in there because it's not easy given the amount of football both teams have played over the past week or with the travel for us.

"Leigh have got a little bit of an advantage playing at home and we know that they make it difficult to win there, but on the flip side we've got a few more players who will be coming back in a bit fresher whereas they're having to use the same players from their squad."

The Robins go into Saturday's match with 10 wins from their 11 matches so far, their only defeat coming at the hands of Toulouse on Easter Monday, and Sheens has recalled eight senior players for the trip to the Leigh Sports Village.
