Matt Dufty will be out of action for up to six weeks after undergoing surgery on a knee problem.

The Warrington Wolves full-back picked up the problem at Magic Weekend, but still scored a hat-trick in his side's 24-6 win over Leeds Rhinos.

Dufty has been a major attacking force for Warrington in their push for the top six this season, scoring 20 tries in 25 appearances in all competitions, and his treble on Saturday was his second of the season.

The injury is a blow to the Wolves, as Dufty is the club's top try-scorer and has made more metres than anyone else in the squad.

Dufty had the knee heavily strapped and hobbled his way through parts of the game against Leeds, but a trip to a specialist revealed the need for surgery, with the club stating he will be missing for four to six weeks.
