Two goals in five first-half minutes secured victory for Huddersfield against nine-man Nottingham Forest.
Danny Schofield raced onto Danny Adams' through-ball and lobbed Forest keeper Paul Gerrard to put the hosts ahead.
Andy Booth headed in from close range to make it 2-0 before substitute Jack Lester pulled one back with a lob.
Lester then picked up two bookings and Forest captain Ian Breckin received a straight red card minutes later for hauling down Gary Taylor-Fletcher.
