Defender Samba Kanoute remains on trial at Edgar Street whereas virtually all of the other trialists seen in the past week or so have left.
Kanoute featured in pictures with the rest of the squad at the Open Day prompting speculation that he may be about to sign a contract with the Bulls.
Manager Simon Davey told BN that Kanoute had not yet signed but they were talking about a possible deal.
Kanoute is a 19 year old Frenchman.
