The 23-year-old former Rotherham United and Buxton forward has linked up with the Pilgrims after they concluded an agreement with Lincolnshire neighbours, Gainsborough Trinity, to complete Walker's transfer.

Walker (pictured), who played under Boston boss Craig Elliott at Shaw Lane AFC earlier last season, scored 4 goals in 19 appearances for the Pilgrims in 2014/15 and made a further nine outings during the 2015/16 campaign.

Elliott has also bolstered his goalkeeping options with the acquisition of teenager Dylan Parkin.

The 19-year-old has linked up with the Pilgrims following his departure from Chesterfield where, despite not making a competitive first-team appearance, was a regular on the Spireites' bench in 2017/18.

Parkin has signed an initial one-year contract at The Jakemans Stadium and will provide competition for George Willis for the number one jersey.

Boston has also snapped up Harrogate Town defender John McCombe.

The experienced 33-year-old helped drive Harrogate towards promotion through the play-offs in 2017/18 and has now penned an initial one-year contract with the Pilgrims.

McCombe began his career at Huddersfield Town and has since played for the likes of York City, Macclesfield Town and Chester FC.
