Middlesbrough 0-0 Ipswich
Middlesbrough remain unbeaten in the Championship but missed out on the chance to go top after an entertaining goalless draw with Ipswich.
Ipswich defender Ibrahima Sonko headed wide from just four yards out after Keith Andrews' clever lofted pass.
Michael Chopra should have scored for Town but his volley from three yards struck keeper Carl Ikeme and flew over.
The visitors' Jason Scotland hit the post with a powerful drive, and Boro's Scott McDonald forced a good save.
Ipswich survived a penalty shout when there was a handball claim against Lee Bowyer and Australia international McDonald had another near miss late on, heading into the side-netting.
Middlesbrough's blank was the first time they failed to score in 21 games but both clubs have now kept three consecutive league clean sheets.
