Harry Kane is expected to be out for up to six weeks after damaging lateral ligaments in his right ankle.
The Tottenham striker limped off in the 4-1 win over Bournemouth on Sunday after tangling with goalkeeper Asmir Begovic.
The club conducted preliminary assessments on Wednesday and announced that they expected him back in training next month.
The 24-year-old was supposed to be sent for a scan on Monday but swelling continued to cause a delay.
