Gateshead manager Ian Bogie has confirmed prolific striker Jon Shaw was withdrawn from Saturday's 2-1 defeat by Wrexham as a precautionary measure.
Shaw, 28, left the field at half-time to be replaced by Gary Mulligan for the second period after completing the first 45 minutes for the Tynesiders.
"Jon's been struggling with a groin problem," Bogie told BBC Newcastle.
"He wanted to carry on, but it's one of those that if he continues he could be out for the Christmas period."
Bogie added: "Bearing in mind our next game is a week on Monday ... he gets all the time to recover.
The former Mansfield striker has scored 23 goals in 27 games for Gateshead this campaign.
Shaw's injury comes as fellow striker Yemi Odubade begins his return to fitness after a broken metatarsal.
Nathan Fisher was injured for the trip to the Racecourse Ground, leaving Gary Mulligan as the club's only other fit centre forward.
