Nuneaton Town have re-signed free agent Donovan Simmons on non-contract terms.
The 23-year-old striker played for Boro during the 2010/2011 season, but left the club to join Dover Athletic.
Simmons, who began his career at Coventry and had spells in Scotland for Greenock and Kilmarnock, was available after his release by Dover in May.
Boro manager Kevin Wilkin told the club website: "He has been training with the team since his return to the area and looks sharp."
He added: "We will look to take him on a non-contract basis and look to see how the situation develops."
