Thierry Latty-Fairweather is expected to miss this afternoon's game against AFC Telford.
The Hereford left back had to be subbed early in the second half last Tuesday at Chorley.
"He is a doubt at the moment," manager Yan Klukowski told BBC Hereford and Worcester.
"But I don't think it is as serious as we first thought.
"We're hoping seven to ten days so fingers crossed for the game next weekend (Darlington)."
Other players with injuries?
"We've got a couple coming back.
"Luke Haines should be back in training next week.
"The same for Orrin Pendley.
"Other than Jack Evans with his long-term injury that should mean that we are close to full strength.
"We try to get him in and around the group just to make sure he's got some good company and that feel good factor around him.
"He's a bright bubbly character so we need him around the group because he's very jovial around the place and he's a really likeable character.
"He's out of his cast, little hurdles he needs to get over in terms of his rehab.
"Hopefully he can get back fit over the next three to four weeks."
