AFC Telford striker Adam Proudlock has been ruled out until at least January.
The former Wolverhampton Wanderers man, 29, suffered a broken ankle in last weekend's FA Cup win over Gainsborough.
"It's bad news for the club and especially for Adam, who'd just got himself back into the team," Bucks boss Andy Sinton told BBC Radio Shropshire.
Proudlock, who joined AFC Telford United last season after leaving Grimsby, helped the Bucks win promotion to the Blue Square Bet Premier.
After overcoming a number of niggling injuries over the summer, he returned to score his first goal for Telford this season at Forest Green last month.
But this latest blow will not help the struggling Bucks, 18th in the table, just two points clear of danger, in their bid to avoid a swift return to the Blue Square Bet North.
"He'll be in plaster for up to six weeks," said Sinton. "Then it depends on recovery time and his rehabilitation programme - but he won't be back until at least the new year."
