Both father and son were unhurt but have been flown to Nairobi for precautionary checks.“It all happened very quickly,” explained Waldegård Snr following the accident. “We were going flat out over a concrete drift. We had a triple caution in the notes so I’m not sure what went wrong exactly but the back end got caught and it flipped the car.“Of course, it’s very disappointing – yesterday was such a good day and everything was going fine and then today this has happened. I am feeling fine but Mathias seems to have a little concussion so the team are flying us to a hospital Nairobi as a precaution.”Team owner Richard Tuthill concluded: “Obviously it’s very disappointing for Björn and Mathias but now our main priority is to ensure they are both thoroughly checked over in Nairobi. I’d like to take a moment to personally thank the excellent medical team on-event: they had flown a helicopter over within minutes of the incident and have done a great job so far.”Waldegård was placed third prior to his retirement and had clocked the fastest time on yesterday’s closing stage.Following Saturday’s opening test, team mate and former winner Stig Blomqvist has resumed his lead on the Safari Classic and is leading Ian Duncan by 31 seconds.0Shares0000(Visited 1 times, 1 visits today) 0Shares0000TANZANIA, November 23, 2013 – Tuthill Porsche driver Björn Waldegård has retired from this year’s East African Safari Classic following a crash on Saturday’s 154 kilometre Jeshini stage in Tanzania.Waldegård and his navigating son Mathias were 8km into the day’s opening stage when the Swedes passed over a concrete drift and rolled their Tuthill 911 one and a half times before the car landed on the co-driver’s side.
