Mauricio Pochettino's side could be without the South Korean star for much of their pre-season due to upcoming surgery on his fractured arm
Son Heung-min will undergo surgery on his fractured arm on Friday and could miss a large part of Tottenham's pre-season preparations for the 2017-18 Premier League campaign.
The forward sustained the injury during South Korea's 3-2 loss to Qatar in World Cup qualifying on Tuesday. Son, 24, was substituted and went down the tunnel to receive treatment after landing heavily on his arm in the 34th minute in Doha.
The former Bayer Leverkusen star, who scored 21 goals in 47 appearances last term, underwent further assessments with the national team and Tottenham have confirmed those scans have revealed a fracture of his forearm.
