AREQUIPA, Peru — Nine-times world rally champion Sebastien Loeb withdrew from the Dakar Rally on Wednesday while defending champion Stephane Peterhansel stretched his lead after the last full stage in Peru. And the rally ended in the dunes for Andre Villas-Boas.

Portuguese soccer manager Andre Villas-Boas has withdrawn from the Dakar Rally after he injured his back in the Peruvian desert. The former Tottenham Hotspur and Chelsea manager, who left Chinese side Shanghai SIPG in November, had entered the 40th edition of the endurance event to mark his 40th birthday.

We jumped off a dune and crashed the car nose first. The Dakar unfortunately is finished for us, he said on Instagram. Better luck next time. Villas-Boas had been driving a Toyota and was running two hours and 18 minutes behind the leader, Peterhansel of France.

Loeb, who won Tuesday's stage for Peugeot and was second overall, halted five kilometers into the 266km stage from San Juan de Marcona to Arequipa, the last overnight stop before the rally enters Bolivia and the high-altitude stages.

He lost two hours waiting for assistance before continuing but, with co-driver Daniel Elena in pain from the jolt in the dunes, had to accept defeat. The sand was extremely loose. We got stuck once and managed to get going again, Loeb told the Dakar.com website before retiring.

We got to a crest where another car was stuck. We were following Nasser (Al-Attiyah) and saw him go over, so we did the same, but I hadn't realized there was a hole behind the crest. And, bam, we went right into the hole.

Right now I'm trying to see how my co-driver's doing: we're driving really slowly and, as soon as I go over 30 kph he screams inside the car, added the Frenchman.

Peterhansel, Loeb's teammate who had been nearly seven minutes clear on Tuesday and is heading for a record 14th Dakar win, took the stage to extend his lead over Spaniard Carlos Sainz to 31 minutes and 16 seconds.

Sainz, also in a Peugeot and a double world rally champion, got bogged down in the dunes early on and was 18 minutes behind Peterhansel at the finish. Dutch driver Bernhard Ten Brinke was third in a Toyota, but more than an hour and a quarter off the pace, with Qatari Nasser Al-Attiyah fourth.

In the bikes category, Yamaha's French rider Adrien van Beveren stayed on top in a stage won by Honda's Spaniard Joan Barreda. Argentina's Kevin Benevides was in second place, a minute behind the leader.

Thursday's sixth stage, with a 313km timed special section, runs from the city of Arequipa and up to the shores of Lake Titicaca before ending in La Paz. — Reuters
