Latrell Mitchell has rubbished claims he is not committed to the New South Wales State of Origin cause after missing out on selection for the series opener.

Mitchell formed a devastating centre combination with Tom Trbojevic as they scored four tries each in a dominant 2021 series win by the Blues, but has not played a game since then due to injuries.

In fact, despite being one of rugby league's most dominant outside backs on his day, Mitchell has only played seven of a possible 18 Origin contests since his debut in 2018, although he has also never played in a losing series.

This year, poor form for the last-placed South Sydney Rabbitohs kept Mitchell out of the side, with new coach Michael Maguire opting for Stephen Crichton and rugby union-bound debutant Joseph Sua'ali'i in the centres.

"Every player is in the mix but, as I keep going back to, it was about how they're playing and how they're performing," Maguire said.

There were reports earlier in the year that Mitchell may make himself unavailable for selection as he tried to revive South Sydney's season.
