Having joined Dewsbury in 2015, 26-year old Grant previously played for Barrow Raiders and South Wales Scorpions, and has represented his native Wales on the international stage – scoring four tries in just five appearances so far.
Grant topped the Rams’ try scoring list in 2015, and his good form continued into the 2016 season – making 22 appearances and scoring 12 tries (again leading the Rams’ tally and indeed ranked in the top ten in the Championship), before an ankle injury prematurely ended his season in June.
“I’ve had a good two years with the boys at Dewsbury and developed as a player, but joining a full-time team is an opportunity you can’t turn down.
“I’ve been watching London’s form this season, and they’ve been really strong – you can tell they’ve worked hard, and they deserve to be where they are.
“I’m excited to make the move south and join the boys. Hopefully I can maintain a good try scoring record and aim for success with the Broncos.”
London’s head coach, Andrew Henderson, believes Grant will further toughen his pre-existing Welsh back line.
“After speaking to him I can tell that he’ll fit really well into the team culture here. I really believe Dalton has the ability and credentials to become a Super League player.
“I look forward to seeing what he brings to our side from 2017.”
