Fahey returned to the team in mid-September, and made seven appearances, four of which were starts. In November, he returned home to Ireland on indefinite compassionate leave for personal and family reasons. After two months away, Fahey took part in pre-season training with Shamrock Rovers, ahead of a full fitness assessment which preceded his return to training with Birmingham in mid-February. However, Fahey was ruled out for the rest of the season in April with a recurrence of a hip problem, having played just twice since his return from compassionate leave. At the end of the season, Fahey announced he was leaving Birmingham as the club had decided not to take up their option to extend his contract.
