RIO DE JANEIRO, Nov. 2 (Xinhua) -- Ronaldinho revealed his relief on Thursday after walking away unharmed from a three-car pile-up that left the driver of another vehicle needing emergency medical treatment.

The 32-year-old was on his way to a training session with Atletico Mineiro in the Brazilian city of Belo Horizonte when his Porsche Cayenne collided with a Chevette before slamming into a truck.

Ronaldinho was in the front passenger seat of the vehicle, which was driven by his personal chauffeur Daniel Candido.

Police spokesman Ederson Miranda Marinho, who was called to the scene of the accident, said the driver of the Chevette was taken to a hospital emergency ward with what was later described as a "minor" neck injury.

"Thankfully nobody was seriously injured," Ronaldinho said on his Twitter account. "My driver Daniel and I had a big fright."

Immediately after the incident Ronaldinho called his Atletico Mineiro teammate Jo, who drove the former Barcelona and AC Milan star to the club's training base.

The two-time FIFA world player of the year is expected to play in Atletico's visit to Coritiba on Sunday.
