Sunderland are defending an unbeaten home record in the play-offs tonight as they look to book a place in the final against Sheffield United.
To overturn a 2-1 deficit from the first leg, Coventry will have to record a first away win in six attempts.
Sunderland's 2-1 win in the first leg was their first victory against Coventry since February 2007, ending a run of 10 games without a win against the Sky Blues (D5 L5).
Coventry have won two of their past five away games against Sunderland in all competitions (D3), having won just one of their first 18 visits to the Black Cats (D8 L9).
