Leyton Orient have handed a new long-term contract to Adam Chambers.
The 26-year-old midfielder, who has also featured in defence, has been a main-stay in Martin Ling's side this term - after joining on an initial season-long deal in the summer.
Chambers has now put pen-to-paper on a two-and-a-half year deal at Brisbane Road.
"Adam has shown himself to be an excellent find, right from when he joined us on trial, and he deserves this extension to his contract," said Ling.
"His levels of performances deserved better terms and this improvement is fully justified by the impact he has had on the team.
"He has gone from strength to strength over the course of the season and he has played a huge role in getting us out of the relegation zone."
