KARANKA’S REVENGE: Boro fall to former manager and his new side Birmingham City
Scott Hogan grabbed the game's only goal in the first half after some exquisite build-up play from the visitors.
Middlesbrough's best chance of the game seen them almost equalise as Sam Morsy's header struck the crossbar but didn't cross the line acording to goal-line technology.
The defeat leaves Neil Warnock's Middlesbrough in seventh - four points off sixth-placed Reading.
