Elliot Lee is off to Blackpool on loan.
He follows Doneil Henry and Martin Samuelsen who have joined Blackburn Rovers and Peterborough United on short term deals.
He will join up with boss Neil MacDonald has worked with the striker before during his time at Upton Park and will be available for Sunday’s derby match with Fleetwood.
The 20-year-old provides Blackpool with another striking option after Kwame Thomas returned to Derby on Thursday.
Lee has played six times for the Hammers including competing over the summer in the Europa League and it is hoped he will bring some goals to a side who have lost their last seven games.
He has previous Football League experience from loan spells with Colchester, Southend and Luton.
