Hall scored his only goal for Stoke in this season's 1-0 win over Derby

Potters boss Tony Pulis confirmed: "His contract was up at the end of the season so we couldn't stand in his way when Coventry came calling.

"They offered him a two-and-a-half year deal and he is returning to his first club and to the one nearest his family.

"We play them on Saturday, but there is a gentleman's agreement that he won't play," Pulis added on City's website.
