It looked like the Teessiders had done enough when Gary O'Neil put them ahead after 58 minutes.

However, Tony Mowbray's side were stunned by two late goals from Shaun Harrad which saw them eliminated from the competition.

Burton manager Paul Peschisolido said: "I feel fantastic, but if you'd have asked going into the last 10 minutes of the game I wouldn't have said so.

"I actually thought we were terrible today. We just didn't perform.

"Defensively we were solid, but on the ball it was a shambles at times. I'm amazed we've won the game, and maybe this will be a turning point for our season.

"Obviously, I'm absolutely overjoyed that we've got through. It's a fantastic result for the club and the fans.

"Perhaps we didn't deserve it, but I'm not complaining because we're in the hat for the next round - and that's unbelievable.

"I'm going to enjoy my afternoon tomorrow looking at the draw. Let's hope we get a big one.

"It's massive for us to get through to the fourth round for the first time in the club's history.

"I'm pleased for the lads because they're an honest bunch.

"Middlesbrough had the lion's share of the possession and we probably shouldn't have won the game.

"But that's the FA Cup for you. It's a leveller and strange things happen and fortunately for us we came out on the right side."

Middlesbrough manager Tony Mowbray rued his side's inability to cope with pressure for a full 90 minutes.

Mowbray said: "Last minute goals are killing us.

"It happened at Elland Road last weekend and it's happened again today.

"If we could have taken a better share of our chances it wouldn't really have mattered.

"They wouldn't have gambled like they did because they would have been two or three goals down and out of it.

"But when a team is only one goal down, they'll always put you under pressure in the last few minutes.

"It's another example of one goal never being enough.

"I don't even think it was a case of them putting us under any sort of pressure. It was just two isolated incidents.

"Even for the seven or eight minutes between their two goals there was only one team trying to score a winner - and that was us.

"Then they get a free kick in the 93rd minute and they scored from it.

"It was a case of two shots and two goals for Burton."
