Rudy Gestede scored five minutes into stoppage time for Blackburn Rovers as they held Middlesbrough to a 1-1 draw at the Riverside Stadium.
Patrick Bamford's goal seven minutes from time looked to have been enough for the home side before Gestede netted with virtually the last kick of the game.
Boro looked dangerous early on and Jelle Vossen found himself in a good position only to be crowded out inside the box, moments before Grant Leadbitter went close.
Vossen then saw his effort cleared off the line before Albert Adomah fired the follow-up effort wide.
Bamford and Daniel Ayala combined well on 22 minutes to feed Leadbitter, but the midfielder could only drag his shot off target.
Ayala, who had earlier been involved in a collision with Gestede, then went close from a corner as Boro continued to pile the pressure on the visitors.
Simon Eastwood, who was making his first start of the season in goal for Rovers, was being kept busy throughout and Bamford forced him into a save with a low shot on 37 minutes.
Eastwood was once again called into action after the restart, denying Bamford seven minutes into the second half.
The Blackburn goalkeeper made arguably his finest stop of the afternoon on the hour mark to parry Vossen's downward header as Boro pushed for the opener.
However, Eastwood's goal was finally breached with just seven minutes of normal time remaining, as Bamford's deflected effort gave the home side the lead that their play deserved.
There was a late chance for Blackburn as Gestede struck the woodwork, and the striker converted deep into added time to give the visitors a share of the spoils in a top-of-the-table Championship clash.
