Millwall and Huddersfield Town have headed into the break level, with no goals in the opening 45 minutes.
Millwall made a bright start with Shane Lowry forcing a clearance from Peter Clarke inside the opening two minutes, before Nicky Bailey saw his sixth-minute effort go wide.
The Lions continued to apply early pressure, as James Henry saw his shot blocked by Jonathan Hogg while Steve Morison headed just wide.
The first on-target effort game from Huddersfield's James Vaughan, but Stephen Bywater was able to punch the ball away.
Morison cleared a Huddersfield corner in the final minute of the half before having a headed effort at the other end of the pitch moments later, but Alex Smithies got a glove to the ball to ensure the scores remained level.
