Tottenham's Son Heung-min could be out for the rest of January with a leg injury, says Spurs boss Antonio Conte.
Forward Son had scans on a muscle problem after "he felt a bit of pain" following Wednesday's Carabao Cup semi-final first leg defeat by Chelsea.
It rules Son out of next week's second leg against Chelsea as well as the north London derby against Arsenal.
Conte said Son "could stay without training sessions" until the mid-season break starts on 24 January.
Son, who is Tottenham's leading Premier League scorer this season with eight goals, started against Chelsea in the mid-week cup game and played 79 minutes before being replaced.
