Huddersfield decided to sack Clark following Tuesday’s 1-0 home defeat to Sheffield United.
The Terriers stated that ‘concerns had been raised over recent weeks’, as the reason for the sacking.
Huddersfield remain four points behind second-placed Sheffield United.
“I am very perplexed as to why I was dismissed as the manager of Huddersfield Town,” read a statement from Clark on the League Managers’ Association official website.
“Needless to say I am extremely disappointed and shocked considering that, with just 16 games left, we are in a such great position to compete for automatic promotion.
“We built on last season’s momentum following the play-off final by creating history in the Football League record books for consecutive unbeaten games. This was an immense achievement by everybody connected with the club.
“I am massively proud of my record with Huddersfield and I enjoyed a fantastic relationship with the players, coaching staff, supporters and indeed everybody at the club. I now wish them all the very best for the future and hope they will ultimately achieve promotion this season.”
