Bradley has represented Northern Ireland at youth level and had a trial at Celtic last season, having also attracted interest from the likes of Newcastle United and Ipswich Town, which suggests he's a good player. He's big and strong and is predominantly a leftback.
Bradley is seen by Saints boss Danny Lennon as a player for the future and he's likely to play for the under-19s this season, while he could also be used to make up the numbers for the under-21 rule. He has played for Cowdenbeath's first team a few times and has also had a couple of loan spells with junior clubs.
Bradley joins Lennon, assistant Iain Jenkins and players Darren McGregor and Paul McQuade in moving from Cowdenbeath to Saints in the last three weeks.
