Lucas Bergvall is set for a spell on the side-lines after he suffered a suspected concussion during Tottenham Hotspur's clash against Chelsea.

Bergvall, 19, was deployed by Thomas Frank to face the west Londoners. However, his evening came to an end after only seven minutes after he was hit in the side of the head by a volleyed clearance from Enzo Fernandez.

He struggled to run in a straight line from that moment and after a brief, pitch-side consultation with Spurs' medical team, he was told he must leave the pitch. The young Swede was heartbroken and frustrated as he was desperate to carry on.

When he was informed he will not be returning to the pitch, the teenager stormed down the tunnel. Bergvall was replaced by Xavi Simons, who was close to joining the Blues in the summer before the Lilywhites coxed him to north London, came on as a concussion substitution.

Due to Bergvall specifically being forced to leave the pitch because of a concussion, there are strict rules in place as to when he can return to training. In 2021, the Premier League overhauled their rules regarding concussed players.

In a bid to bring their approach in line for the International Football Association Board (IFAB), it was decided teams should be allowed to replace concussed players, without it counting as one of their five substitutions.

The intention behind this alteration was to ensure teams do not find themselves numerically disadvantaged due to a concussion. Raul Jimenez's head injury against Arsenal when he was at Wolves, which saw him miss several months of football, prompted the rule changes.

Any incident is assessed by an independent tunnel doctor, who investigates the footage of the incident.
