Heung-Min Son could be sidelined for three months following surgery to his right forearm, according to The Times.
If true, the attacker would miss the opening month of the new Premier League season.
Son fractured his arm after falling heavily while playing for his country last week. The Korean Football association initially claimed he would be out of action for around a month after his surgery.
But The Times believes the 24-year-old could miss up to three months of action, meaning he will be absent for the entirety of Tottenham’s pre-season campaign.
