The move allows him the opportunity to play his football closer to home next season with Nuneaton set to be in the Premier Division Central following their relegation from the National League North.
The former Wrexham and Tamworth player joined the Glassboys in August 2018 after a short spell at Stratford Town and he netted 5 times in 38 appearances for the Club (30 + 8 sub).
We wish Callum well with his new club and thank him for his services during his nine months with the Glassboys.
