Two goals from George Boyd on his full Hull City debut has helped the Tigers to a 3-0 half-time lead over Birmingham City.

Boyd opened his account for the Tigers with little more than a minute on the clock, turning in Robbie Brady's cross from 12 yards out.

Lee Clark's side could have drawn level six minutes later when Nikola Zigic tested David Stockdale with a close-range header, but they fell further behind in the 11th minute.

Mohamed Gedo beat Jack Butland with a low effort from 12 yards out after latching onto David Meyler's pass to double the home side's advantage.

Boyd's second of the afternoon put Hull well in the driving seat. The striker guided Ahmed Elmohamady's pass into the net in the 33rd minute to make it 3-0 at the break.
