Terry’s car struck a Chelsea security guard as the defender left the club’s Stamford Bridge stadium, following their defeat to Inter Milan.
A Chelsea spokesman said: “We can confirm there was an unfortunate accident as John Terry left Stamford Bridge last night.
“When driving out of the stadium at approximately 1-2 mph in a queue of traffic exiting the ground, his car was surrounded by photographers and fans.
“In the melee that ensued a member of Chelsea’s security staff was knocked to the ground, making contact with the car. He suffered a badly bruised leg.
“John was aware at the time that there was a lot of contact with his car during the incident, but not that anyone was injured as a result.
“Upon hearing of the injury, John spoke to the police. He has also been in contact with the staff member to check on his welfare.”
