Palace youth academy graduates Jerome Binnom-Williams and Jake Gray have left the club on free transfers.
Jerome Binnom-Williams joined League One side Peterborough United. The left-back has signed a two-year contract with Peterborough, joining the League One side having come through the ranks at Palace.
Binnom-Williams made his professional debut for Palace in 2013 against Bristol City in the League Cup, but has not made the breakthrough to play in the Premier League.
Binnom-Williams has, however spent several spells away from the club on loan, at Forest Green Rovers, Southend United, Burton Albion and Leyton Orient.
Fellow academy graduate, Jake Gray has signed a permanent deal with Luton Town after he was initially set to move there on a loan move, before he was informed it was turning into a permanent deal.
The attacking midfielder, who featured for the Crystal Palace first team two years ago, spent time on loan at Hartlepool United last season and had been playing for the Eagles’ U21 side this pre-season.
In both cases it is thought the club let the academy graduates leave so they could kick-start their career.
