Huddersfield boss Lee Clark slammed his side's poor defending after they lost 4-3 on penalties to Bradford in the Johnstone's Paint Trophy.
Huddersfield midfielder Tommy Miller's 63rd-minute penalty cancelled out Antony Kay's own goal and then skipper Peter Clarke ensured extra-time after Bradford had regained the lead through Luke Oliver.
Substitute Nialle Rodney converted the winning spot-kick in the shoot-out for Bradford, who also beat Sheffield Wednesday on penalties in the last round to go through.
Clark said: "This is the second home game in a row when we've scored twice, but not won the match. We seem to be too easy to get at across the back. We're going to have to rectify that.
"We cannot keep needing to score three goals to win a game at home. There's a lot of work to do."
Clark added: "Despite the defending, I thought we still had enough chances to win the game, but we weren't clinical enough. I'm disappointed to lose the tie. We wanted to stay in the competition as I thought our run last season helped us."
