Greg Abbott hailed Huddersfield goalkeeper Ian Bennett for two wonder saves which led to his side's 2-0 away defeat.
Bennett saved twice from Francois Zoko with the game still goalless, leaving Gary Roberts to win it for the Terriers with a first-half brace.
Abbott said: "They were wonder saves and saves change games.
"If one of those had gone in it would have been different. After that Huddersfield scored two quality goals and they then won it a bit cosily. We didn't cause them enough problems, which is a bit disappointing."
He added: "We just needed something to spark us off but we never quite got up a head of steam.
"We played too many long balls and we stopped playing the type of football that we have been doing."
