Southgate dislocates shoulder
Gareth Southgate has suffered a dislocated right shoulder while running near England's World Cup base in Repino.
The England boss was making the most of a day off from training when he sustained the injury, which left him in a local hospital.
English Football Association team doctor Rob Chakraverty attended to oversee the treatment and Southgate returned to camp in good spirits but sporting a black sling.
Southgate took his tumble light-heartedly, joking he may not be allowed to show the same kind of emotion on the touchline which accompanied Harry Kane's stoppage-time winner against Tunisia.
"I might not be celebrating any goals as athletically in the future," he said.
"The doc has made it clear that punching the air is not an option. I am just a bit gutted because I was on for my record 10k time!"
Southgate's unexpected injury news caused no great disruption to team plans - with a scheduled meeting taking place on time in the evening as preparations for Sunday's Group G clash with Panama continue.
"We are lucky we have a top-class medical team around us, so it was fine," Southgate said.
"I had brilliant help from them, and I am just sorry that I managed to ruin their day off."
Southgate joins Dele Alli on England's walking wounded list, with the Tottenham forward suffering from a quad complaint.
