Tottenham will be missing one of their first team stars when they travel on their pre-season tour of Singapore and Shanghai.
Eric Dier will not be present when the club travel out to the far East next week, due to injury.
Although what the injury is, is unknown.
Dier had a stop-start 2018/19 campaign, having three separate spells on the sidelines.
He missed four games in October and November with a thigh muscle strain, before suffering with appendicitis and needing an appendectomy, which kept him out for more than a month.
Towards the end of the season he suffered a hip injury too, which led to another month out.
The 25-year-old would have been hoping to get the 2019/20 campaign off to a strong start, but another problem could hamper that now.
The first team players only returned to pre-season training this week, with new signing Tanguy Ndombele joining up with his new teammates for the first time at Hotspur Way.
But Dier has had to undergo a "medical procedure" for a mystery problem.
In a short statement on the club's official website, Tottenham said: "Eric Dier has undergone a medical procedure to correct an issue detected during medical assessments on the first day of pre-season training.
"Following the successful procedure Eric will now undertake a short period of rehabilitation. He will therefore not travel on the club's pre-season tour to Singapore and Shanghai."
Despite the injury, Dier is expected to return before the start of the new season.
