London - Swansea striker Bafetimbi Gomis has suffered a serious health scare that overshadowed Tottenham's 3-2 win at White Hart Lane on Wednesday.
Gomis collapsed and needed treatment for several minutes before being rushed to hospital for tests.
The south Wales club later revealed that France international Gomis was in a stable condition, but the incident marred an otherwise entertaining encounter.

But Ryan Mason restored Tottenham's lead and Andros Townsend added the third soon after.

After an emotional pre-match tribute to Dave Mackay, the club's legendary former captain who passed away on Monday, Spurs fed off the charged atmosphere as they roared into a seventh minute lead.

Tottenham's ideal start quickly became an after-thought as Swansea striker Gomis collapsed when the players were making their way back for the restart.
Gomis, who had fainted during matches several times in the past, was attended to for four minutes and left the field on a stretcher, by which point he was conscious and wearing an oxygen mask.
When the game resumed, Swansea didn't seem affected by a worrying moment that recalled the time when Bolton midfielder Fabrice Muamba suffered a cardiac arrest, which he eventually recovered from, during an FA Cup tie at Tottenham in 2012.

Townsend took full advantage as he surges forward, cut inside a defender and curled home.
Sigurdsson's 89th minute strike set the stage for a nervous last few minutes, but Spurs held on.
