Leyton Orient have offered one-year professional contracts to second year scholars Harry Lee and De’Reece Vanderhyde. 

Midfielder Lee and defender Vanderhyde were both on the bench in Saturday's win at Coventry City and the pair will be part of the first-team squad next season.

Orient have released Joe Foley, Sean Grace, striker Afolabi Obafemi and George Wickings but Harrison Georgiou has been invited back to pre-season with a view to earning a longer contract.
