Jazz arrived at Haverfordwest County in March 2021 after leaving Cardiff City, for whom he represented 47 times. A 14-cap Wales international, his arrival at the club was one of the biggest transfers in the history of the Cymru Premier, and has since brought valuable added attention to the club and the league. In April 2022, the defender netted a hat-trick in the 6-1 win against Cefn Druids at The Rock – his first senior goals in a 13-year career to date.
