Defender Peter Gilbert has today been drafted in by manager David Holdsworth with the left-back joining the Club on a non-contract basis.
Hexham-born Gilbert started his career as a trainee with Birmingham City but it was at Plymouth Argyle where the full-back made his Football League bow at the beginning of the 2003/04 season.
A successful loan spell at Home Park brought about a permanent move and he became a regular as Argyle won the Second Division championship, earning the first of eight Welsh U21 international caps in the process.
His impressive form earned him a six-figure move to Leicester City in the summer of 2005 but after just a handful of appearances he was loaned to Sheffield Wednesday before making the move to Hillsborough permanent.
After spending three years with the Owls, Gilbert (29) went on to play for Doncaster Rovers (loan), Oldham Athletic and Northampton Town before spending the last two seasons at Southend United.
He has been handed squad number 30 and will go straight into the squad for Saturday's visit of Luton Town to The 12th Imp Sincil Bank Stadium.
