England coach Gareth Southgate was taken to the hospital after dislocating his right shoulder while running near the team's World Cup base.
The English football Association says Southgate's arm was in a sling when he held a planned team meeting with his players on Wednesday.
Southgate says "it is better this is me than one of the players."
The coach was treated in the hospital with the assistance of England team doctor Rob Chakraverty.
Southgate says "I am just a bit gutted because I was on for my record 10-kilometer time."
England opened Group G with a 2-1 win over Tunisia and next plays against Panama on Sunday.
