Danny Ward was on target for Huddersfield Town as they head into half time with a 1-0 lead at Ipswich Town.
The home side started on the front foot, firing a warning shot inside five minutes as Luke Chambers's long-range effort whizzed past the post.
Huddersfield had their fair share of attacking possession, but Ipswich came close again in the 20th minute when David McGoldrick's shot on the turn was kept out by Alex Smithies.
The Terriers threatened in the 23rd minute as a dipping strike from Oliver Norwood cleared the crossbar, with Ipswich keeper Dean Gerken saving well from Ward moments later.
Huddersfield were awarded a penalty in the 24th minute when Christophe Berra brought down James Vaughan in the box, but Gerken saved the former Everton striker's resultant spot kick.
Mark Robins's side edged their noses in front 10 minutes before the break through Ward, who turned in Adam Hammill's cross to make it 1-0 at the interval.
