Swindon Town fear striker Jonathan Obika could be out for up to three months with a shoulder injury.
Obika was hurt in the first half of Saturday's 3-0 win at Barnsley and will see a specialist on Wednesday to assess the problem further.
The 24-year-old striker has been in excellent form since joining the League One club from Tottenham for an undisclosed fee on 1 September.
He has scored five goals in five appearances for Mark Cooper's Robins.
The win at Oakwell, which put Swindon third in League One, was the first game in which had failed to score this season.
