Stevenage midfielder James Dunne has been ruled out of action for "two or three weeks" with an unspecified injury.
It is believed that the 23-year-old, who has scored one goal this season, suffered the injury during training last week.
"It will keep him out for two or three weeks," Stevenage manager Graham Westley told the club's official website.
Stevenage currently sit 16th in the League One table.
