Middlesbrough wasted a chance to boost their survival bid as the Premier League strugglers were held to a 0-0 draw by relegation rivals Swansea on Sunday.
Steve Agnew's side would have moved within two points of safety with a victory at the Liberty Stadium.
But instead second-bottom Middlesbrough remain five points adrift of 17th placed Swansea after a nervous, error-strewn encounter.
Middlesbrough, without a win in 12 league games, are four points behind third-bottom Hull, although they have a game in hand on both sides in the battle to avoid dropping into the Championship.
It was also a missed opportunity for Swansea, who could have pulled clear of the bottom three but instead remain deep in trouble themselves, just one point above Hull following their third successive game without a win.
