Huddersfield Town and Charlton Athletic head in at half time with the score at 0-0.
The Terriers came close to taking an early lead when Adam Clayton's shot was cleared off the line before Peter Clarke missed an open goal on the rebound.
Charlton got their first chance at the other end when Ricardo Fuller robbed Joel Lynch, but the Jamaican's shot was well blocked.
The away side went down to ten men after 34 minutes when Keith Southern saw red for a foul on Michael Morrison, leaving the Huddersfield bench furious.
The half-time whistle blew to bring a goalless 45 minutes to a close.
