Newport County captain Aaron Wildig face a spell on the sidelines after suffering concussion.
Former Cardiff midfielder Wildig was substituted with a head injury during Saturday’s 4-0 League Two defeat at Swindon Town and faces a mandatory spell out of action.
Newport assistant coach Dafydd Williams said: “It is concussion. We have revisited that through the protocols the medical department do and had it confirmed.
“I think it’s 12 days Aaron will be out for and there is a return to play protocol to abide by.”
Wildig, 32, will miss the trip to Barrow and will be monitored before Newport host Crewe, on September 28.
His absence is another injury blow for Newport who have suffered two successive league defeats, after winning three in a row – with Wildig scoring in each of the victories.
Newport have a clutch of players out with injury. The latest casualty is Newcastle loan midfielder Jamie Miley, who has had a hernia operation and could be out for a month.
The Wildig situation was revealed after Newport earned a much welcomed 1-0 EFL Trophy victory over West Ham United under-21s at Rodney Parade, on Tuesday night.
Willliams said the win over West Ham, Newport’s first victory in this season’s competition was important.
He said: “We were bitterly disappointed with the last two league games, especially Saturday.
“But ultimately it was about bouncing back from that and showing that grit and resilience that ultimately when you represent this football club you have to have as a non-negotiable.
“We fell short of that on Saturday and it was all about that (against West Ham) and to be fair the boys delivered.”
