However, Gomis was allowed to play on despite losing consciousness.
The Frenchman has a history of fainting after being diagnosed with a low blood pressure condition in 2009.
He fainted while with the Swans during a match against Tottenham in 2015.
Bafetimbi Gomis sahada fenalaşıp kısa süreli baygınlık geçirdi. Ben canlı izlerken çok korktum. Büyük geçmiş olsun. Doktor müdahalesinden sonra yeniden oyuna devam ediyor pic.twitter.com/fVEtpV4iud
