Sherrell Assidjo departs following an impressive performance at Welling in the FA Cup win on Saturday.
Boro received an approach for Sherrel and the former Farnborough and Dulwich winger has decided to leave.
Manager Steve Baker explained “ I’m extremely disappointed with his decision as he had no club a month ago and asked me for a chance. I gave him that and five games later he has left. With our recent form and still being in the cup I though he may have stayed, but I was wrong. However no hard feelings and I wish him all the best. It happens , we move on and he will be replaced."
