Full-time: Huddersfield Town 2 Middlesbrough 2
ALBERT ADOMAH rediscovered his scoring touch to help Middlesbrough end a long wait for an away goal, even if a much-needed victory continued to evade the men from Teesside.
Huddersfield Town took the lead twice through former Boro loan player Adam Hammill and then Nahki Wells, only for Boro's African to grab a goal in each half to secure a point.
His first, a simple tap in after capitalising on a mistake from Huddersfield's Oscar Gobern, was Middlesbrough's first away goal in more than seven hours of football.
It also marked the end of his own drought dating back to December 29 and, when he added his second shortly after half-time, the 26-year-old took his tally for the season to 11.
But the brace failed to give Middlesbrough the edge to go on and win for only the second time in 12 matches, meaning another game to close the gap on the play-off places has slipped away once more.
There are still 13 points separating Middlesbrough from the top six with just eight matches remaining.
An inability to overcome a Huddersfield side, whose fans got frustrated at times, with just one win from their last ten has merely hammered home the point that Championship football will again be at the Riverside next season.
That was also the case days earlier following defeat to Queens Park Rangers. If Dimi Konstantopoulos had hoped for a good start following the embarrassment of Saturday's horrible bobble goal, it never arrived.
Just moments after Alex Smithies was almost humiliated at the other end by his decision to dally in his own box under pressure from Danny Graham, the Terriers made the most of a blunder from Nathaniel Chalobah in the middle.
Just 132 seconds had gone when Chalobah, on loan from Chelsea, gifted possession to the home side's midfielder Gobern in the centre circle when his attempt to turn routinely ended with his touch losing complete control.
The ball quickly moved on to Oliver Norwood, who spotted space in between Ben Gibson and Kenneth Omeruo and slid a delightful pass in behind the defensive pairing.
There was still work to be done but Hammill, who spent time on loan at Middlesbrough two years ago, picked out Konstantopoulos' bottom right corner with a low-drilled finish.
Yet rather than build on that, Huddersfield allowed Middlesbrough to pull level pretty soon after. Jacob Butterfield had already wasted a great chance from 12 yards from Adomah's centre before the latter equalised.
The Ghana international should never have been given the opportunity. Gobern's ridiculous back pass when he was hardly under any pressure was weak, Adomah nipped in, rounded Smithies before slotting in to an empty net.
Given there had been two goals inside the opening ten minutes, Middlesbrough looked bright enough and gaps appeared often enough to suggest there would be more goals.
But in the remaining 35 minutes of the opening half only Huddersfield looked like changing the scoreline and could have had more than the one Wells struck.
While a harmless Graham acrobat kick seconds before the break was all Karanka's side conjured up before heading for the dressing room, Huddersfield created plenty.
Winger Danny Ward was particularly lively and was afforded too much freedom to turn when he drifted inside to try his luck, often getting a shot or pass away. He made Konstantopoulos make a save at his near post after bursting down the right.
That arrived just two minutes after Huddersfield had reclaimed the lead – and in style.
Wells, who interested Middlesbrough in January before Bradford accepted a £1.3m bid from South Yorkshire, made the most of the space in front of him on the edge of the area.
After turning on to his left, he curled a brilliant finish in off the inside of Konstantopoulos' far post.
The only positive Middlesbrough, who had gifted Huddersfield the ball again in the build up when Adomah conceded a silly throw-in, could take at the break was that they only trailed by one.
But Karanka's decision to replace Chalobah with the more attack-minded Lee Tomlin brought immediate rewards. Norwood's awful pass dropped straight to Adomah 70 seconds after the restart.
Middlesbrough's leading goalscorer opened up his legs to run in to space before drilling an unstoppable equaliser beyond Smithies from 20 yards.
There was greater urgency in the way Middlesbrough played in the second half, with Butterfield looking for a forward pass from the deep-lying midfield role he was asked to play alongside Dean Whitehead following Tomlin's introduction.
But Huddersfield still threatened occasionally, chiefly through Hammill, while there was very rarely any shots directed on Smithies' goal in front of the travelling supporters.
By the time the whistle was blow at the end of the game, a draw was probably a fair outcome, but once again Middlesbrough missed another opportunity to give their run-in a lift.
