Brighton defender Adam Webster is out for the time being due to ankle ligament damage.
Webster came off during his side's game against Norwich City last weekend.
He is definitely out of the game against Manchester United on Sunday at Old Trafford.
The club will assess him over the international break to see how quickly he can respond to treatment.
Albion boss Graham Potter told reporters: "He has had a good week, responded quite well to everything.
"It is not too bad at this stage."
When asked about a timetable for his return, Potter continued: "I don't like a timescale on it but around that.
"Sometimes with ligaments, you can be talking months.
"Hopefully it is weeks but we don't like to lose anybody."
