McAllister heads for Vale exit
Sean McAllister will leave Port Vale this month after the club opted not to extend his contract.
The midfielder sees his current deal expire on January 8 but manager Micky Adams has decided not to table fresh terms, leaving McAllister free to find another club.
"It's unfortunate that we weren't able to offer Sean more first-team opportunities but that underlines the competition for places we have among the squad," Adams told Vale's official website.
"He's a great professional and we wish him the very best of luck for the future."
McAllister joined Vale on a short-term contract at the start of November but has made just three appearances, two of those coming off the bench.
