BBC Radio Stoke have reported that Port Vale are awaiting news of a scan on an injury sustained by Adam Yates.
The radio station says that Yates sustained the injury during the midweek game against Nottingham Forest.
The concerns are that the veteran defender may have sustained cruciate ligament damage.
If true, the news would be a bitter blow for the club’s longest-serving player who only agreed a new one-year contract in the summer.
Under Bruno Ribeiro, right-back Yates has been used as left-back cover and his absence will leave Vale short in that department especially as Kiko has also picked up an injury.
