The popular Centre Half told the club website: "Since moving here from Cardiff I've seen how big the club is, the potential it has to progress and the set-up here at the stadium.
"I had this season left on my existing contract and with the injury I had last season I sat down with the manager and he was true to his word that it would all be sorted.
"It's great that it has all been sorted quickly and I can now concentrate on the future."
