Wigan coach Brian Noble has come out fighting after a week of adversity to claim his side can still make history.

The Warriors have not played for a fortnight but have dominated headlines with second row Gareth Hock failing a drugs test and Noble's own position coming under scrutiny.

England international Hock has been provisionally suspended, pending analysis of a B sample, after testing positive for cocaine.

Noble, whose contract expires at the end of the season, has also had to deal with reports claiming the club recently offered his job to New Zealand coach Stephen Kearney.

The former Bradford and Great Britain boss has put on a brave face through all the turmoil to insist his prime concern is bouncing back from a shock loss to Celtic Crusaders.

"It doesn't change what we have got to achieve at the weekend," said Noble, whose side travel to Hull KR in the engage Super League on Sunday.

"We are actually in a cleansing period from our last performance.

"We have had some tough luck, the news [Hock] on Tuesday was shocking, to say the least, but we have trained really tough.

"We have just got to get on with things. Contrary to what people are saying about the demise of the place, it might be our finest hour.

"Our attitude in south Wales was extremely poor and it has to be a whole lot better.

"We have seen the composition of the league this year, if you can put three or four wins together it propels you four or five places up the ladder.

"We are in charge of this particular chapter of the club's history and I'm extremely confident we can do well."

Wigan are just outside the play-off positions and also have a Carnegie Challenge Cup semi-final to look forward to.

Wigan were beaten 20-12 when they last played Rovers in May and the Robins remain third in the table despite a recent dip in form.

Elsewhere Warrington could give Brian Carney a debut as they host Hull while Harlequins will look to get back to winning ways at Wakefield.

Warrington claimed an uplifting win over Catalans in Barcelona last week and are now ready to welcome former Wigan and Hull winger Carney following the end of his rugby union commitments.

The Wolves are level in the table with Hull, who edged past Salford 14-12 for a morale-boosting win last week after losing nine of their previous 11.

Hull coach Richard Agar said: "It probably wasn't the greatest win in the history of the club but our first-half performance gave us signs for encouragement.

"We just needed that to instil a little confidence and that know-how of how to get over the finish line.

"Warrington are very strong up front. Adrian Morley sets a terrific lead for them and [former Hull player] Garreth Carvell, as we know very well, can make some very damaging charges.

"But we got close to them last time and we should be confident of putting a performance in."

Hull's build-up was affected when a number of players went down with a sickness bug earlier this week but Agar reports the problem has now cleared.

Harlequins' recent charge up the table was halted as champions Leeds won convincingly at the Twickenham Stoop last week.

The Londoners slipped to fifth but remained two points above this weekend's opponents Wakefield, who did not have a game.

Wildcats coach John Kear said: "I think Harlequins, Hull KR, Huddersfield and ourselves will probably feel the happiest of all the teams in the accounts we have given ourselves up to now.

"I'm certain Harlequins will come and be very feisty. They have been good all season, they are very consistent and work hard.

"But there is also a good feeling at Wakefield because we are sixth in the table and there are only 10 games left.

"Before the season all the media said we'd come 12th, 13th or even bottom.

"We think we have done OK but we know it counts for nothing unless we come home with the wind in our sails."
