Duke made 59 appearances for Hull over seven years
Bradford City have signed unattached goalkeeper Matt Duke on a two-year deal.
The 34-year-old left Hull City in the summer after making 23 appearances last season in the Championship.
The Bantams have also clinched the signing of Tigers winger Jamie Devitt on loan until January and have signed unattached pair Terry Dixon and Dean Overson.
Devitt, 21, played 18 games for the Tigers last season.
But he has made just one appearance this season -
in the Carling Cup tie against Macclesfield
Ex-Stevenage striker Dixon, 21, has agreed a one-year deal while versatile defender Overson, 18, who was last with Burnley, has signed a two-year deal.
Dixon has immediately joined non-League side AFC Halifax on loan.
Meanwhile, the Bantams have confirmed that former caretaker boss Colin Cooper will stay at the club as assistant manager.
