The Sky Blues forward then had plenty of time to compose himself before striking the ball past Josef Bursik with his right foot for his eighth goal of the season.
Portsmouth attacker Adrian Segecic was forced off with 15 minutes remaining, limping off the pitch minutes after coming on and in some pain after winning a foul for his side.
