The 24-year-old Blues keeper only moved to the Ricoh Arena on an initial one month loan deal on Tuesday and played in their 2-0 Carling Cup defeat against Morecambe the same night.
However, with new signing Ben Foster having had to return from England international duty with a back injury and Maik Taylor most likely to be in action for Northern Ireland tonight (Wednesday) then Blues have recalled Doyle from his loan spell at the Sky Blues.
