Marc Marquez reached another milestone in his shoulder recovery by returning to motocross training fo🎃llowing the Qatar season opener.

The reigning five-time MotoGP champion once again narrowly lost out on victory to Andrea Dovizioso in the Losail night race and certainly didn't look ham𝓀pered by the left shoulder, following December's surgery to prevent further dislocations.

Marquez then gave the shoulder a further workout 🧔with a heavy landing on the motocross track (see below).

"The time between the two races has bee♒n good, I was able to return training with a motocross bike and I feel confident for this race," said Marquez, ahea꧟d of this weekend's second round in Argentina.

“We started well in Qatar and fought until ♔the end for victory. The goal is of course t🧸o do the same in Argentina and take as many points as possible."

Argentina 2018: Three penalties in 24 laps

Marquez b♌egan last year's Argentina MotoGP as the pre-race favourite, but went on to receive no less than three penalties by the end of 24 chaotic laps.

It all began when Marquez stalled his Repsol Honda at the start of the (delayed) warm-up lap, leaping from his machine before managing to bump start the engine, turn the bike around anꦺd return ꧟to his grid slot.

That's not allo๊wed and a ride-through penalty was issued, dropping Marquez from 1st to 19th place.

The second penalty came while charging back up the order, when Marquez barged into Aleix Espargaro at the penultimate turn, resultin෴g in a 'drop one place' penalty.

But it was the third infringement that made headlines around the world; Marquez's uneasy truce❀ with Valentino Rossi being shattered when he launched his RCV inside the Italian at the same penultimate turn.

Contact was made and, although both stayed upright, Rossi ran wide onto the wet grass and fell. The Italian remounted to finish 19th, while Marquez was relegated from fifth to 18th after being slapped with a 30-second penalty𓃲.

Marquez's immediate attempt t🏅o apologise was furiously dismissed outside the Yamaha garage by Uccio, while Rossi later unleashed both barrels to the media, labelling Marquez a 'dirty' rider who has 'destroyed our sport', adding that the Spaniard makes cont🌄act deliberately and 'hopes you crash'.

Marquez felt he had done 'nothing crazy', while E🌜spargaro added that he was hit harder by Danilo Petrucci than M🦹arquez.

Meanwhile, fellow Honda rider Cal Crutchlow won𒆙 the race, although Marquez set the fastest lap by 0.484s and, at times, he had been riding 1.5s faster than the rest of the field.

Marquez also tangled with Ros✅si in Argentina durꦦing the 2015 race, on that occasion it was the Spaniard who was thrown from his RC213V as they crossed paths on the exit of the hairpin.
