Striker Lamin Colley has left Scarborough Athletic just days after agreeing to sign.
The former Stockport County man has opted to sign for Conference North club Boston after originally committing to boss Steve Kittrick's side.
Kittrick said: "He said he was going to sign for us, Boston from the Conference North came in for him and he decided to go there instead.
"It is the nature of the beast at this level of football unfortunately.
"The one positive we can take out of this is that Conference North players do want to sign for us."
