Newport County are waiting to discover the extent of on-loan defender Janoi Donacien's ankle injury.
Donacien, on loan from Aston Villa, was taken off on a stretcher after losing his footing during the first half of the 2-2 draw at Accrington Stanley.
The 22-year-old left the Crown Ground on crutches and is set to have a scan on the injury.
"He looks a bit sore and he could be out for a while," manager John Sheridan said.
"We don't want it to be serious but he's in a bit of pain and we'll have to assess him."
Sheridan's side extended their unbeaten run to five games in League Two with a 2-2 draw at high-flying Accrington on Saturday.
Newport twice led through goals from Yan Klukowski and Scott Boden, before Matt Crooks rescued a point for Accrington.
"It's a shame we didn't hang on," Sheridan said.
"It was a good solid performance and that will be a good point hopefully come the end of the season.
"I'm getting quality performances, which gives you a better chance of winning games."
Newport host Brackley Town in the FA Cup first-round replay on Tuesday and are home to fellow League Two strugglers Yeovil Town next Saturday.
