Former Leyton Orient midfielder Solomon Shields is among a handful of trialists hoping to earn a deal at Boston United.
The 23-year-old has most recently been in action for Evo-Stik Southern League side St Albans City.
Shields was among the band of squad players and hopefuls who reported for pre-season training at RAF Cranwell on Saturday.
But one player who won’t be linking up with the club is Josh Wilde.
The left back was among manager Dennis Greene’s top targets.
But - because he’s under the age of 24 - he wouldn’t be able to leave Gainsborough Trinity without compensation being paid.
United made Trinity an offer which was refused at the Northolme, with Wilde accepting a second offer to stay with the Blues.
“I hear that we were offering lots more money than Gainsborough,” Greene said with a smile.
“Our offer that we agreed was a lot less than both the offers that Gainsborough made, so that shows the lad wanted to come and sign for Boston.
“Unfortunately, we couldn’t agree a deal (with Trinity).”
