Paul Coutts denied Middlesbrough the chance to climb to eighth in the Championship table as his late equaliser earned Derby a 2-2 draw and a first point on Teesside in 12 years.
Theo Robinson saw his early penalty cancelled out by Lukas Jutkiewicz in the 19th minute, the Polish striker teeing up what would have been a seventh straight defeat for the Rams at the Riverside with an unchallenged header in the final stages.
However, Boro failed to contain their opponents at the death, Coutts keeping Tony Mowbray's men tethered to mid-table until the weekend at least.
Managerless Blackburn saw their winless streak extended to three games as Nottingham Forest claimed a 0-0 draw at the City Ground.
A share of the spoils was enough to move Rovers, who have temporarily installed Eric Black at the helm following Steve Kean's resignation last week, back into the play-off spots, but they missed the opportunity to move into the top two.
It was Forest who will feel they did more to earn a victory, though, with Paul Robinson saving brilliantly from Lewis McGugan on the stroke of half-time.
