Nottingham Forest are considering signing a replacement for Manchester United loanee Dean Henderson this January.
Henderson, who joined Nottingham Forest on a season-long in the summer, sustained the injury in his side's recent 2-0 win against Leicester. The goalkeeper managed to continue until the final whistle but looked uncomfortable at full-time.
The 25-year-old was assessed after that game and scans revealed he had suffered a grade two tear in his thigh.
