Middlesbrough boss Steve Agnew was left frustrated after their stalemate with Burnley.
Agnew was convinced last man Michael Keane should have been sent off for an 85th-minute foul on substitute Patrick Bamford as he threatened to go one-on-one with keeper Tom Heaton with a chance to secure a priceless win.
He said: "Patrick, I knew when he went on that he's capable of getting on the last man and balls in behind. He's a threat and that's exactly what happened.
"From where I was standing, I was disappointed with the decision. I thought he was in on goal, I thought his first touch was terrific. His dropped on his right foot, he was in control of the ball - he'd have had a one-v-one with the goalkeeper."
Agnew's mood was not improved seconds later when Alvaro Negredo, who had earlier forced a stunning save from Heaton with an acrobatic volley, had a goal chalked off for handball, although he had no issue with that decision.
Agnew said: "Alvaro did everything right, scissor-kick, left foot, lots of power behind it, great save. Stewart Downing steps up and does everything right, Lowton drops on to the post, sees it out for a corner.
"They're just things that have just not gone for us today. But in terms of effort, commitment, attitude, energy... and I have to say the crowd was terrific. It was a proper team effort, really."
