London Broncos prop Jon Wallace has signed a new two-year deal with the Super League club.
The 19-year-old academy product made his debut for the relegation-threatened side earlier this season.
"He's played six Super League games so far this season and has been impressive in all. He has a great work ethic in training and on the pitch," coach Joe Grima told the club's official website.
"Jonathan has come through the junior ranks at the club which gives us extra satisfaction that we have some good systems in place to produce such talented players."
The Broncos currently sit at the bottom of the Super League table, having lost all 15 of their games since the start of the campaign.
They return to action on June 13 with a trip to Wakefield Trinity Wildcats.
