Released Blackpool defender Phil Doughty has been confirmed as one of the three mystery trialists from last night.
The 21 year old had nine games in League Two during loan spells at Accrington and Macclesfield last season after he was told of his release by Blackpool, but failed to secure a deal at either club. He played for Blackpool as a 16 year old in the FA Cup in December 2002.
The other two trialists, who wore no.19 and no.20 last night, have not been named but all three are unlikely to resurface for the Bulls again with Graham Turner's response to a question from the official site of whether any of them taking his eye being a simple "No".
