The medical emergency at the game, which took place around the 42nd minute, caused the whole match to be suspended whilst the supporter was treated.
Spurs defender Eric Dier could be seen gesturing for medical staff to get a defibrillator, proving the severity of the situation.
Both team doctors and other medical staff rushed into action, and appear to have helped the situation greatly.
Newcastle United FC tweeted: "The supporter who was in need of urgent medical assistance has been stabilised and is on their way to hospital.
"Our thoughts are with them."
Tottenham also tweeted out an almost identical tweet, confirming that the supporter was being taken to hospital for further care.
At the restart of play, with the score at St James' Park 2-1 to Tottenham, a round of applause went up for the medical teams for their quick thinking.
Spurs then extended their lead before half-time, making the score 3-1 at the end of an extended first half.
However, the most important thing remains that the supporter could be helped and got to hospital quickly and safely.
Newcastle took an early lead in the fixture through striker Callum Wilson, but his early effort was cancelled out by Tanguy Ndombele.
Spurs and England captain Harry Kane then scored a second for Spurs, his first goal of the season so far, before Son Heung Min then gave his side a two-goal cushion after the short enforced break.
The game is Newcastle's first fixture since the recent controversial takeover that saw long-time owner and Sports Direct owner Mike Ashley leave the club, much to the delight of many Toon fans.
The takeover, fronted by Amanda Staveley, sees the club immediately become one of the richest in the world after being backed by Saudi Arabian money.
It remains to be seen what will happen, but fans will expect to see large amounts of money spent to acquire talent, as well as dreaming of challenging for major honours once again after many years of mediocrity.Featured Image Credit: PA
