Goalkeeper Howes joined West Ham United at U10 level from Crystal Palace. The England U19 keeper has failed to agree new terms and is free to leave the club. Howes has just completed a loan at Conference South side Hampton and Richmond Borough.
Hammers forward Djair Parfitt-Williams signed his first professional contract with West Ham in 2015. The youngster who was born in Bermuda but raised in the United States, was first spotted by the Hammers while playing for San Jose Earthquakes.
Former Ipswich Striker Sam Ford signed a one-year professional contract with the Hammers following a successful trial last year. The club has an option of another year which looks unlikely to be activated.
