Wigan Athletic are sweating on the fitness of on-loan Newcastle United forward Haris Vuckic.
Vuckic suffered an injury in Saturday’s 3-2 defeat to Port Vale.
And the forward left Vale Park wearing a protective right boot.
And Wigan manager Gary Caldwell said: “It looks like an ankle injury. How bad it is, we’re not sure yet.”
Vuckic joined Wigan on a season-loan loan earlier this month.
The 23-year-old spent the last half of last season at Scottish Championship side Rangers.
