Youngsters Sean Scannell and Lee Hills have committed themselves to Crystal Palace until 2012.
The academy graduates, yet to feature this season through injury, signed extensions to their current contracts which were due to run out in the summer.
Manager George Burley has yet to see Hills, 20, in action because of the knee ligament injury that has kept him on the sidelines since April, while 21-year-old Scannell has just returned to full training following a knee injury sustained in pre-season.
"It is great news," said Burley after the players put pen-to-paper.
"They are two young players who have been out for a long time with injury who have committed themselves to another year.
"They are both very talented.
"I do not know Lee particularly well myself as I have not seen too much of him but everyone speaks very highly of him.
"He is very much an attacking left back and I am looking forward to seeing him when he is back, which probably will not be for another six to eight weeks at least.
"Sean is just getting back into full training.
"I have seen little bits of him in pre-season and he is another player that has shown he will have a big future.
"He can score goals and is very much an attack-minded forward so we are very pleased."
