On 29 July 2010, Doyle had a trial with Plymouth Argyle, playing 45 minutes of a friendly against Hereford United, but no deal materialised, and on 10 August 2010, Doyle signed on loan for Coventry City. He was signed as emergency cover while Keiren Westwood was away on international duty, coming in for the League Cup match against Morecambe, but was recalled only a day later because of an injury to Foster. In January 2011, Doyle played his first match for Birmingham for nearly two years in a 3–2 defeat of Coventry in the FA Cup fourth round, and kept his place for the fifth-round tie against Sheffield Wednesday, keeping a clean sheet as the home team won 3–0. After his appearance for Coventry versus Morecambe earlier in the season Doyle was cup-tied for Birmingham's victorious run in the 2010-11 Football League Cup; for the final Foster started and Taylor was on the bench. He made his first Premier League appearance since August 2007, as a first-half substitute for the injured Foster, in a 5–0 defeat at Liverpool in April in which he conceded three goals.
