World champion Marc Marquez has won the season-opening Qatar MotoGP Grand Prix just a month after breaking his leg.
The Honda rider fought off a thrilling, wheel-to-wheel challenge from nine-time champion Valentino Rossi on a Yamaha to win by a quarter of a second.
Dani Pedrosa, on the second factory Honda, took third.
Marquez, who broke his right leg in a dirt-bike accident in his native Spain at the end of February, came into the new season having become the youngest ever world champion in 2013.
Rossi, seeking what would have been his 81st win in the elite MotoGP class, said he could take a lot out of the race, having been written off last season as a spent force.
2-time world champion Jorge Lorenzo, who started 5th on the grid, grabbed the lead on the first bend, but then fell before they'd completed their first lap.
