After coming through the club's youth ranks, Turnbull signed a professional contract with Middlesbrough in 2002. He represented England U20 in the 2003 FIFA World Youth Championship.
In July 2007 it was announced that Turnbull had signed a season long loan deal at Football League Championship side Cardiff City. He was signed as a replacement for long-serving Neil Alexander, who left the club after a contract dispute, and began the season as first choice goalkeeper for the club but due to some errors in his opening games he was replaced for the 2–2 draw with Preston North End by Michael Oakes and spent the remainder of his loan spell on the bench before he was recalled by Middlesbrough on 5 October 2007 following an injury to second choice keeper Brad Jones.
The recall was made by mutual consent between the teams. After being recalled, Turnbull played in two of Middlesbrough's games in the absence of first choice goalkeeper Mark Schwarzer who had broken his thumb in training. One was Boro's win over Arsenal at the Riverside Stadium on the 9 December 2007, the score being 2–1.
After more than 11 years with Middlesbrough, Mark Schwarzer left the club during the summer of 2008 to join Fulham. Middlesbrough manager Gareth Southgate decided not to buy a new keeper and allow Turnbull and Jones to fight it out for the number one position. Although Jones played the first game of the season, Turnbull was in goal for Middlesbrough's 2–1 defeat at Liverpool the following week, when Jones injured himself in the warm-up.
