Nick Blackman’s goal gave Reading a narrow win over their Championship counterparts Huddersfield.
After a scrappy first half James Vaughan spurned the game’s best chance, heading over at the back post from Jack Robinson’s cross from the left byeline.
Blackman finished low into the corner after Hal Robson-Kanu’s pass with the game’s only shot on target.
Jonathan Hogg picked up a late second yellow card as Huddersfield fell short.
With just a point separating the two sides in the middle of the Championship it was always likely to be a tight match and the first period saw no goalmouth action.
In a contest short of chances Vaughan should have tested Royals goalkeeper Mikkel Andersen when he was picked out by Robinson’s back-post cross.
But Royals boss Steve Clarke replaced Jamie Mackie, who had been booked on the stroke of half-time, with Blackman at the break and the change proved crucial.
Reading moved the ball quickly from a throw-in and Robson-Kanu played in Blackman, whose low left-footed shot beat goalkeeper Alex Smithies.
Hogg received a second yellow card following an altercation with Danny Williams in the closing minutes as the lacklustre hosts failed to threaten Reading’s goal.
