Blackburn Rovers 0-0 Coventry City: ten-man Sky Blues deny hosts crucial win
Blackburn failed to achieve the win which would have made certain of their place in the Championship next season despite Coventry being reduced to 10-men for the last half-hour.
Liam Kitching was sent off for a professional foul on Sam Gallagher as the Rovers striker was about to go clear of the defence.
Blackburn earlier had manager John Eustace red-carded following a scuffle with Kasey Palmer as the Sky Blues player went to retrieve a ball.
Results elsewhere meant a Blackburn winner would have made them safe ahead of next week's final day, but Tyrhys Dolan hit the post as Coventry held on for a point.
The draw means Blackburn face a nervous last-day fixture at promoted Leicester, needing a point to be safe.
Failure to get a result at the King Power Stadium would mean they have to rely on Sheffield Wednesday losing and Birmingham and Plymouth not winning their final games.
Blackburn are on a dreadful run at Ewood Park, with just one win in their last 11, and they were hoping to improve that against a Coventry side still reeling from a tiring and emotional week.
The Sky Blues were dramatically denied a place in the FA Cup final by a penalty shoot-out defeat by Manchester United last weekend and then saw their play-off hopes disappear with a home loss to Hull in midweek.
Rovers made most of the running, but Sammie Szmodics failed to add to his remarkable 31-goal tally for the season and Coventry keeper Brad Collins did well to save a Dolan shot, the best chance of the first half.
The game heated up five minutes into the second half as Eustace, trying to get the ball off Palmer, was shown a red card, the Coventry player receiving a yellow for his part in the scuffle.
Liam Kelly hit the post for Coventry but minutes later Kitching was dismissed and that signalled an all-out assault on the Coventry goal.
Szmodics curled a shot just wide, Dolan hit the post and had a loud penalty appeal after going down in the box, and Yasin Ayari and Andrew Moran both went agonisingly close.
