27-year-old Jack began his career with West Bromwich Albion and had loan spells with Accrington and Crawley before joining Southampton for two years. He has been at Walsall for the last three seasons, the first on loan. 

Matt said: ”I’ve crossed paths with Jack before when I was at Crawley and have followed his career. He’s a good character who Andy Little knows well, and is coming in to his peak years as a goalkeeper so will be fighting for that position.”
