Port Vale terminate contract of midfielder Gary Roberts
Gary Roberts has had his contract terminated by Port Vale following a second breach of club discipline in the space of three months.
The 24-year-old midfielder was suspended for two weeks by the League Two club in September after failing to report for a training session.
The former Crewe trainee then reported unfit for duty on Wednesday.
"This behaviour is unacceptable and cannot continue," manager Micky Adams told the official website.
"Although Gary has talent on a football pitch, we have given him numerous second chances off it, in addition to offering him help with his personal issues.
"Footballers are role models and their responsibilities extend far beyond the pitch.
"Therefore, we have been given no other option but to terminate his contract immediately."
Roberts, who has suffered from gambling and drinking problems, left each of his three previous clubs, Crewe, Yeovil and Rotherham, after discipline breaches.
He started the season in excellent form, scoring five goals in his first nine appearances.
However, he did not report for training the day after a 3-2 home defeat by Shrewsbury on 17 September and arrived unfit for duty the following day.
Roberts was placed on the transfer list by manager Micky Adams, but was able to force his way back into the first-team squad, although he has been limited to two starts in the FA Cup and two substitute appearances in League Two since completing his ban.
