Dwight Gayle has given Peterborough United a 1-0 lead over Leeds United at half time in their game at Elland Road.
Michael Tonge had a good chance early on for the home side, but Robert Olejnik gathered the ball to prevent the goal.
Peterborough were awarded a free kick in a dangerous position after Tommy Rowe was fouled, but Paddy Kenny was able to save Lee Tomlin's effort.
The visitors kept the Leeds keeper busy early on, as Kenny had to stop a Gayle shot from 12 yards out, but the striker got he better of Kenny in the 15th minute, blasting the ball into the top left corner from close range.
Tomlin almost doubled the advantage for Peterborough five minutes later, but he scuffed his shot straight to Kenny.
Tonge, Ross McCormack and Tomlin all had good chances to get the home side back on level terms, but Leeds could not find an equaliser before half time.
