Kozluk has played in the top four English divisions over his career
Bradford City have completed the signing of experienced defender Rob Kozluk on a short-term deal until the end of the season.
The 34-year-old right-back joins on a free transfer after leaving fellow League Two side Port Vale last month.
City manager Phil Parkinson said Kozluk would provide useful cover in the absence of regular right-back Simon Ramsden, out with a broken toe.
Kozluk spent nine years with Sheffield United over two separate spells.
Parkinson told the club website
: "Rob is a hugely experienced defender who can play in a couple of positions along the back four, and I am looking forward to working with him."
