Half-time: Rams level at Boro after short-lived lead
DERBY County's lead was short-lived at the Riverside Stadium as the first half of their Championship clash with Middlesbrough ended 1-1.
Theo Robinson put the Rams ahead from the penalty spot after a quarter of an hour but Lukas Jutkiewicz levelled for Boro only three minutes later.
Robinson and Nathan Tyson were both recalled to the Derby starting line-up as Nigel Clough made two changes to his side following Sunday's 1-0 win at Nottingham Forest.
The strike duo replaced the injured Jamie Ward (hamstring) and Conor Sammon, who dropped to the bench.
Also among the Derby substitutes was teenage forward Mason Bennett, who became the Rams' youngest ever first-team player when he made his debut at the Riverside Stadium last season.
Tyson started wide on the left, with Will Hughes moved into a three-man central midfield.
Boro had the first effort on goal in the sixth minute, when Jake Buxton's slip allowed Grant Leadbitter to get a low shot in but Frank Fielding saved comfortably.
Moments later, Robinson did well after latching on to a flick from Tyson but Seb Hines came across to block his strike.
Nicky Bailey prodded wide from 20 yards, while Richard Keogh sliced over his own bar following a dangerous free kick into the box.
Derby won a penalty when Bryson exchanged passes with Robinson and was then taken out in the area by Andre Bikey.
Robinson had missed from the spot in the League Cup defeat to Scunthorpe United but stepped up and finished well past Jason Steele, low into the corner.
The Rams' lead did not last long, though.
Keogh was adjudged to have fouled Jutkiewicz 25 yards from goal.
Leadbitter's free kick was parried by Fielding but he did not manage to push the ball away from danger and Jutkiewicz bundled the rebound in from close range.
Jutkiewicz had another chance soon after but his hooked effort from Justin Hoyte's cross lacked power and was easy for the keeper.
After Hughes had fired over, play was brought back for a foul on Robinson and Paul Coutts felt his free kick had been handled as it was blocked by the defensive wall.
Luke Williams volleyed inches wide in the 32nd minute after George Friend had headed back across goal.
At the other end, Jeff Hendrick played in Robinson, whose toe poke was stopped by the legs of Steele.
Bikey tested Fielding from distance but the sides went into the break on level terms.
