Crystal Palace defender Reece Hannam has signed a contract extension that now runs until June 2023, with the option to extend by a further year.
Hannam, 20, has impressed with his exemplary attitude since joining Palace last summer, and recently featured as an unused substitute for the Premier League clash with Fulham.
The left-back has been a key member of Shaun Derry's Under-23s squad this season, playing 11 games and claiming four assists so far.
Derry said: "Reece is an exceptionally hard-working individual who is demonstrating high levels of maturity, determination and understanding of what is required to play for our football club since joining last year.
