GEORGE PORTER has agreed a three-year contract with npower Championship side Burnley.
The 20-year-old winger turned down a much improved contract offer from the O’s earlier in the close season and has now penned a deal to take him to Turf Moor.
Having offered Porter a new contract, the O’s are entitled to compensation for his transfer and discussions between the two clubs regarding an agreeable level of compensation are ongoing.
Porter was Russell Slade’s first signing as O’s boss when he made the move from non-league Cray Wanderers to Brisbane Road in May 2010.
He quickly made his first team debut, coming on as a sub in an early-season defeat to Charlton Athletic, but then spent most of his first campaign with the club furthering his development with loans at Sussex clubs Lewes and Hastings United.
The Sidcup-born forward returned to make an impact with the O’s in pre-season ahead of the 2011/12 campaign and soon began to feature more regularly in the first team.
He went on to make 38 appearances last term, 26 of them coming from the bench, with two goals to his name.
Meanwhile, Matthew Spring has signed for League 2 outfit Wycombe Wanderers following the end of his contract with the O’s.
The 32-year-old midfielder made 95 appearances for the club across his two years in E10.
