Norwich had been promoted to the Premier League during Lafferty's absence. He scored his first goal of the 2015–16 season in a 3–0 League Cup victory against West Bromwich Albion, but found regular games hard to come by. In November 2015, Leeds United head coach Steve Evans revealed he had inquired about the availability of Lafferty on loan. However, Lafferty remained with Norwich until 24 March 2016, when he joined Championship club Birmingham City on loan until the end of the season.
