The visitors opened the scoring in the 20th minute as a long ball from on-loan goalkeeper Vito Mannone caused havoc in the Boro defence and when the ball came out to Robert Koren, the Slovenian's shot from 20 yards somehow managed to find a way past Jason Steele.
But the home side responded with their first chance of the game as Leroy Lita headed in a Tony McMahon cross to level the scores just before the half-hour mark.
The Tigers should have gone in front when Marvin Emnes gave the ball away to Liam Rosenior, whose low cross was palmed away by Steele into the path of Nick Barmby but the veteran could not hook the ball into the empty net.
Hull regained the lead four minutes before the break as Steele failed to keep out Gerrard's glancing header from a Koren free-kick.
Middlesbrough rallied after the interval and equalised instantly when Scott McDonald headed in from close range after good work from Lita.
