Swansea City will be waiting to hear on the severity of Bafetimbi Gomis's hamstring injury after the striker was forced off after 15 minutes during his side's 1-1 draw with Everton.
The French striker is Garry Monk's main attacking option up front, after Wilfried Bony was able to seal a £28m move to Manchester City in January.
However, Gomis is repaying Monk's faith as he has now scored four of his five Premier League goals since Bony's move.
"Bafe felt a tightening of his hamstring. He will have a scan. Hopefully it's not too serious. We don't want to lose his quality and we're already quite thin on the ground," Monk said, according to Goal.com.
Aaron Lennon opened the scoring for the Toffees in the lunchtime kickoff, before Jonjo Shelvey equalised from the penalty spot to earn both sides a point.
