Tottenham forward Son Heung-min is likely to be out for some time with a hamstring injury, according to Jose Mourinho.
The South Korea international was substituted at half-time of Sunday's 1-1 Premier League draw with Newcastle United at the Tottenham Hotspur Stadium.
Son, who twice hit the woodwork in the first half after Lucas Moura opened the scoring, was replaced by Steven Bergwijn for the second period, with the match finishing in controversial fashion when Callum Wilson equalised with a 97th-minute penalty after Eric Dier was punished for handball via a VAR check.
