Young goalkeeper Charlie Grainger has joined Cray Wanderers on a one-month loan deal
The second year scholar who featured in the first team squad on a number of occasions last season made his debut for the Ryman Premier League club on Saturday in their 4-1 win over Met Police.
Orient goalkeeping coach Kevin Dearden said: "Charlie's gone there for a month with a view to making that a longer period. It was felt that he needed to go out and experience regular men's football to aid the next stage of his development."
Grainger is the latest O's player to head out for experience in the non-league pyramid as De'Reece Vanderhyde continues to perform for Concord Rangers whilst Harrison Georgiou remains at St. Albans on loan.
