Hull's teenage hooker James Cunningham has joined London Broncos on loan for the 2014 season.
The 19-year-old academy product is in his second season as a full-time professional with the Black and Whites and played in the club's recent friendlies against Doncaster and Bradford.
Hull head coach Lee Radford said: "This is a great opportunity for James to take the step up to the next level and play Super League week in, week out."
Cunningham made his Super League debut for Hull in 2012 but his only appearance last season came in the Challenge Cup.
He is the third-choice hooker behind Danny Houghton and Aaron Heremaia but Hull will be able to recall him if required at a month's notice.
London have already secured the services of Leeds trio Alex Foster, Thomas Minns and James Duckworth on season-long loan deals as they look to rebuild at the new home in Barnet.
Meanwhile, the Broncos have confirmed veteran Australian prop Ben Ross has pulled out of a move to Super League.
In a statement, London said: "The club had agreed terms with Ben but he has decided to stay in Australia to take up the opportunity to be welfare manager with Men of League.
"London Broncos would like to wish Ben all the best in his new role."
