Tottenham Hotspur have been dealt a potentially huge injury blow regarding Son Heung-min.

What's the latest?

Speaking in the post-match press conference following Spurs' victory over Olympique de Marseille last night (via the Evening Standard), assistant manager Cristian Stellini revealed that the forward - who was withdrawn in the first half after a clash of heads with Chancel Mbemba - may have suffered a concussion at the Orange Vélodrome.

Regarding the 30-year-old's injury, the Italian coach said: "In this moment, we don't know [the extent of Son's injury]. We have to wait for a medical assessment, and we have to wait until tomorrow [Wednesday].

"Sonny feels better now. I saw him in the dressing room. He celebrated with us. So we will wait for tomorrow. We are not sure [if he was concussed]. It is his face. His eye is a bit swollen."

Huge blow

Considering just how dazed Son looked when leaving the pitch on Tuesday night, it would appear incredibly likely that the 30-year-old had indeed suffered a concussion - something that, due to the concussion protocol, would see the attacker ruled out of action for at least six days, resulting in the South Korean missing Spurs' Premier League meeting with Liverpool on Sunday.

And, considering the fact that both Dejan Kulusevski and Richarlison are also injury doubts for the visit of the Reds this weekend, the additional absence of Son would certainly come as a huge blow to Antonio Conte and his side.

Indeed, while the £43m-rated talent has not always been at his free-flowing best over his 13 Premier League appearances this season, he has still highly impressed, scoring three goals, registering two assists and creating two big chances, as well as taking an average of 2.8 shots - 1.3 of which have hit the target - making 2.2 key passes and completing 0.7 dribbles per game.

These returns have seen the £190k-per-week attacker average an extremely impressive SofaScore match rating of 7.23, not only ranking him as Spurs' third-best player in the league but also as the joint 30th-best player in the top flight of English football as a whole this term.

That comes after a campaign in with the forward was simply mesmerising in the final third, romping to the Premier League Golden Boot, scoring a huge haul of 23 goals in the top flight.

As such, it is evident that Son's loss would come as a huge blow to Tottenham's chances of picking up a positive result against Liverpool on Sunday, especially if both Kulusevski and Richarlison remain out.
