Former NRL star Josh McGuire has been sent off in his Super League debut for the Warrington Wolves during a 22-10 trial victory over the Leigh Leopards.

McGuire, who split his NRL career between stints with Brisbane, North Queensland and St George Illawarra, signed a two-year deal with 'the Wire' back in July last year, tying him to the Wolves through to the end of 2024.

His signature adds to a major ex-NRL contingent in Warrington, joining the likes of Peter Mata'utia, Matt Dufty, George Williams, Sam Kasiano and Paul Vaughan at the northern English club.

McGuire was shown a red card late in the contest for dissent towards the referee, however Warrington head coach Daryl Power was unsure what was said during the contest.

โ€œHe said something but I'm still not entirely sure what it was. I need to find out more about that one because to be honest, I've no idea at the minute," Powell said in the post-match press conference.

"We'll get to the bottom of that one. We don't really have any evidence of what's been said at the moment. We'll find out during the week.โ€

Having already lost Wales international Gil Dudson in the same match to a broken hand, Warrington's middle third is looking thin as McGuire awaits the Match Review Committee's punishment.
