"The Rebels" retained the provincial title in 1976 following a 3–15 to 4–5 defeat of Limerick once again. It was McDonnell's fourth winners' medal. Wexford provided the opposition in the subsequent All-Ireland final on 5 September 1976. Wexford got off to a great start and were 2–2 to no score ahead after just six minutes. Wexford had a two-point lead with ten minutes to go, however, three points from Jimmy Barry-Murphy, two from Pat Moylan and a kicked effort from Ray Cummins gave Cork a 2–21 to 4–11 victory. It was McDonnell's second All-Ireland medal.
