The New Zealand-born 26-year-old will link up with the Broncos for pre-season training at the end of 2014.
Foran had a previous stint at Salford City Reds in the Super League during the 2013 season, and also played for Manly Sea Eagles and Melbourne Storm in the NRL.
“I’m really pleased that the deal is done and I’m extremely excited about becoming a London Broncos player and seeing what next year holds,” said Foran.
A key factor in Foran’s signing was head coach Joey Grima’s plans for the future of the Broncos: “I’ve been in constant contact with Joey Grima throughout our contract talks and I’ve really got a good understanding about his plans for the future and how passionate he is towards success,” he said.
Foran is confident he can help the Broncos and hopes to prove some people wrong: “I know that I have come a long way in my rugby league in the last 12 months and I’m very confident that I can play some really good footy. Hopefully along with my fellow team-mates we can string some wins together and build some confidence as a club.
“I’m looking forward to the challenge having already played in the UK for Salford in 2013 where things didn’t quite go to plan. I’m determined to play some really good footy that I know I’m capable of.”
