Chambers (pictured), 31, moves to Silverlands from Brackley Town.

He had signed for the Northamptonshire outfit in August 2020 from Vanarama National League North rivals Kidderminster Harriers, who he had signed for from Nuneaton Borough on a two-year deal ahead of the 2018/19 season.

He can name Grimsby Town, York City, Dagenham & Redbridge and Leicester City amongst his former clubs, the latter of which he holds the record for the club’s youngest first-team player aged 15 years and 203 days.

Middleton joins the Bucks from league rivals Grantham Town where he spent a year.

The 26-year-old, who is capable of playing at right-back or centre-half, emerged from Doncaster Rovers' youth set-up to make numerous appearances for North Ferriby United and Scarborough Athletic before a move to Harrogate Town in the summer of 2017.

He joined National League North side Boston United on an initial month's loan from Harrogate in December 2017 having also spent a brief loan spell with Buxton prior to his arrival in Boston.

After being recalled just days into his second month with the Pilgrims, he returned for a fresh loan spell in March 2018 and then signed permanently in the summer of 2018 before moving to Grantham.
