Ten-man Blackburn lost further ground on the Championship's top two as they were beaten by in-form Middlesbrough at Ewood Park.
Ryan Hedges was left all alone to latch onto John Buckley's long ball and fire Rovers into an early lead from the edge of the box.
The visitors levelled just seconds into the second half when Matt Crooks found the run of Marcus Forss, who smashed a superb shot across goalkeeper Thomas Kaminski into the far corner.
Moments later Rovers midfielder Buckley was sent off for throwing the ball at Riley McGree's head, and the Australian soon took full advantage with a superb volleyed winner into the top corner.
