Huddersfield Town have confirmed that Mark Hudson has completed his move to the club from Cardiff City this evening.
The Championship side announced that the defender has agreed a two-year contract for what has been described as a "nominal undisclosed fee".
The club's caretaker manager, Mark Lillis, told the club's website: "The club has stayed patient to bring in the right man to improve the central defensive options and that has been rewarded with this arrival of Mark this evening.
"Organisation and experience are very important attributes in the heart of your defence and Mark has both in abundance. He is a leader with vast experience of the Championship and is a massive arrival for this football club.
"There are not many centre backs of his type and quality around, he can be a hugely influential addition. Huge credit has to go to the staff behind the scenes for getting this deal over the line amid considerable competition from some big clubs in this division, it's testament to the ambition at Huddersfield Town."
Hudson has made over 300 appearances during his spells with Cardiff, Crystal Palace and Charlton Athletic.
