London Broncos have confirmed Jason Golden, Rob Thomas and Lamont Bryan will leave at the end of the season when their contracts expire.
Second row Golden endured an injury-hit 2011 campaign and has scored one try for nine appearances this time around.
Bryan and Thomas have both been on dual registrations with London Skolars this season but will not be resigned by the Broncos for the 2013 season.
Broncos head coach Tony Rea has thanked the trio for their efforts and has wished them all the best for the future.
"I'd like to thank the guys for the efforts put in since being at the club," he told the club's official website. "We all wish them the best for next season and beyond."
