Midfielder Gavin Johnson has quit League One side Colchester. The 34-year-old has been offered a six-month contract with League two side Boston United.
He told BBC Essex: "I felt by playing 44 games last season, I'd done enough to get another year - and the manager said he wanted to keep me.
"But I don't think the chairman wanted to up the offer of six months. I've signed for another club, but I'm sorry to be leaving Colchester."
