Paul Gascoigne has signed a deal to become a player-coach for Boston.
Gascoigne has also played for Middlesbrough and Everton
Full details of the 37-year-old former England midfielder's contract will be confirmed next Tuesday, reports BBC Radio Lincolnshire.
Gascoigne earned 57 caps with England and was one of the stars of the 1990 World Cup and Euro 1996.
But the former Newcastle, Tottenham, Lazio and Rangers star had been without a club since ending a stint as a player-coach in China last year.
His last English club was Burnley two years ago, and a trial spell with Wolves last November failed to earn him a deal.
Gascoigne said this week that he was determined to succeed at York Street, adding: "I know I'm going to be watched over the next five or six weeks.
"I'm not daft. I need to do the right things for myself, the manager Steve Evans and the chairman Jon Sotnick."
He played 75 minutes in Boston's 4-0 friendly win against an inexperienced Newcastle XI on Tuesday.
Afterwards Gascoigne said: "It's opened my eyes a bit in terms of wanting to play football again.
"Another couple of games and a bit of short stuff, I'll be up with the rest
of the lads.
"It was nice in the dressing room, listening to Steve talk to the lads and
seeing cups of tea everywhere, little things like that which I had for 20 years.
Little things like that give me a buzz back."
