London Broncos skipper Matt Cook has agreed to join Castleford Tigers on a two-year deal from the start of the 2015 season.
Cook, 27, has played all 22 games for the Broncos this term and becomes the latest player to agree a switch to another Super League side ahead of next season.
Speaking to the club’s website, the Warrington-born centre said: "This is my third season with the Broncos and I've had a fantastic time down in the capital during those three years.
“It's the most settled and most welcome I've probably felt and that goes for both me and my wife.”
The former Hull KR and Bradford Bulls player continued: "I'm sorry that I couldn't lead the club to a bit more success and to survive relegation. It's going to be sad leaving on a sour note but I do believe in what Joey Grima is doing at the club.
“Off the field the club is going in the right direction and is being run really well.
"As bad as it looks at the moment I wholeheartedly believe they will be able to bounce back from relegation,” said Cook.
Signed from Hull KR in 2012, Cook has gone on to make 51 Super League appearances for the Broncos since, scoring six tries for the Londoners.
It has also been confirmed Scott Moore will leave The Hive at the end of the current campaign too.
