Chelsea captain John Terry broke the leg of a security guard while driving out of the club’s Stamford Bridge ground last night’s Champions League defeat to Inter.
Police said the man broke his leg but the club claim it was badly bruised.
It said Terry, who drove off, was aware of “a lot of contact” with his car but assumed no one had been hurt.
A Metropolitan Police spokesman said Terry was later breathalysed by Surrey Police at his home in Oxshott and investigations were continuing.
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.”
Metropolitan Police said: “A 35-year-old man suffering a broken leg was taken by ambulance to a west London hospital where he is in a stable condition.
“The 4×4 car did not stop at the scene. Inquiries into the incident continue.”
