The 25-year-old, who has scored three tries in nine appearances this season, will join the Broncos for the 2020 campaign.

Meanwhile, have released prop Mitch Clark, 26.

The club say they have allowed Clark, who is joining Wigan at the end of the season, to leave early in order to “pursue another short-term playing opportunity.”
