Crystal Palace Development pair Sam Woods and Luke Dreher have both signed contracts extensions with the club, running until June 2021.
Woods, 21, made his first-team debut appearance at Middlesbrough in the Carabao Cup in October 2018 as a substitute, before being awarded a first starting berth for the cup clash against Colchester United earlier this season.
Midfielder Dreher, 20, earned his first senior appearance in the 5-3 Premier League victory over AFC Bournemouth in May 2019, before sustaining an injury during pre-season.
Speaking after the pair put pen to paper, Chairman Steve Parish said: "We are pleased to reward Sam and Luke with new contracts, and that we are continuing our proud history of developing talented footballers that have risen through our Academy ranks.
