MICHAEL Monaghan could be a doubt for Warrington Wolves’ Super League clash with Castleford Tigers at The Jungle on Saturday, kick off 5.45pm.

The Australian scrum half collected a shoulder injury in the first half of the quarter-final success over Hull Kingston Rovers at the weekend and was in some discomfort with it as he left Craven Park.

Monaghan, seen on the touchline testing his shoulder on a tackling bag at half time, bravely overcome the weakness and pain he was feeling as he returned to the field in the second half to play his part in keeping Wolves on the Wembley trail.
