Midfield duo Ben Watson and Tom Soares have committed their future to Palace by signing extended contracts.
Both had been linked with moves away from Selhurst Park during the close season, but have stuck with the club and contributed to a flying start to the season.
Soares' new deal will keep him with the Eagles until 2010, while Watson's contract ties him to the club until at least 2009.
Also signing is 18-year-old striker Charlie Sheringham. Teddy's son had previously been on a month-to-month deal, but after impressing in training he has been rewarded with a two-year deal.
