Marc Marquez will miss his home MotoGP race after it was confirmed the eight-time world champion will sit out the Spanish Grand Prix this weekend.

The Respol Honda man underwent surgery last month on a right hand fracture, with his recovery keeping him out of both the Argentine Grand Prix and Grand Prix of the Americas.

There had been some hope the Spaniard could return in Jerez, but the decision has now been made to focus on next month's French Grand Prix.

"Yesterday, we did another CT scan, and it has been confirmed that, despite the fact that the injury is progressing favourably, the bone has not yet finished healing and racing in Jerez was risky," Marquez said on Wednesday.

"Together with the medical team, we decided not to take any risks, to wait two more weeks and return in Le Mans.

"I am very sorry to miss the Spanish Grand Prix because it is always special, because of the atmosphere, racing at home and above all, seeing and enjoying the fans.

"I will continue with the rehabilitation and work to be back as soon as possible. Thank you for your messages of support!"

Iker Lecuona will stand in for Marquez this weekend.

Miguel Oliveira won a delayed Indonesian Grand Prix on Sunday as he held off a late surge from world champion Fabio Quartararo.

Quartararo had qualified in pole position but dropped to fifth in the difficult conditions as Oliveira built what proved to be an unassailable lead.

Champion Quartararo was on a run of four consecutive races without a podium finish but produced a brilliant ride in the second half of the race to take second ahead of Johann Zarco.

Jack Miller, who led in the early stages, finished fourth and Alex Rins fifth, with Enea Bastianini, winner in Qatar's season opener, down in 12th.

Six-time world champion Marc Marquez was forced to miss the race after a heavy crash during the warm-up left him with concussion.

The action got underway after more than an hour's delay, during which torrential rain fell and lightning struck the edge of the track, with the race shortened to 20 laps.

Miller and Oliveira pulled away from Quartararo after adjusting more quickly to the conditions and the latter surged into the lead as his pace became too much for the Australian.

Jorge Martin crashed at Turn 1 after catching a puddle with his front wheel, highlighting just how treacherous the track remained even after the rain had ceased and the surface began to dry.

Quartararo overtook Rins with eight laps to go before passing Miller and Zarco in a gripping battle for a podium place, the French rider eventually pulling away.

There was not enough time to catch Oliveira, though, the Red Bull KTM man claiming his fourth career win in exemplary fashion.

Marc Marquez dedicated his German Grand Prix victory to all those who had helped him during his recovery from a broken arm.

Six-time MotoGP champion Marquez sustained the injury following an accident in the opening race to the 2020 season in Jerez, before then suffering a further setback when a plate inserted into his fractured humerus became damaged.

After sitting out all of last year and then also the opening two rounds of the 2021 campaign, the Spaniard finished seventh and ninth upon his return before enduring three successive retirements, leaving him short of form and way down the list in the standings.

However, a visit to Sachsenring saw Marquez rediscover his best form as he completed an 11th successive win at the track, with this latest triumph his eighth in a row in the top category.

There were understandably emotional scenes after he crossed the finishing line as he not only ended his own personal drought but also the long wait for success for his team, Honda having not prevailed at a race since Valencia in 2019.

"It's true that it was, and still is, a hard time in my career, so this victory helps a lot," said Marquez, who appeared in tears on the track before joining in emotional celebrations with his team ahead of the presentation ceremony.

"When you are in a hard situation, when you have had three crashes in a row, it's not easy mentally or physically. But when I crossed the line I thought of all the people who had helped me be there, because in such a situation it is impossible to do it alone.

"You need the team, the doctors, the physios, the manager, your family and friends, everybody that helps you. They were helping me a lot, and have helped me a lot to come back.

"Today is a time to enjoy and say thanks to all of them, specifically Honda. The respect they gave me during all of this year was something I appreciated a lot. 

"This will be a great and important victory for me, but also for the Honda family."

Honda have won 17 of the past 23 MotoGP races at Sachsenring, with Marquez's latest victory making it 11 in succession at the venue.

Marquez moves up to 10th in the championship standings as Frenchman Fabio Quartararo leads the way, his advantage over compatriot Johann Zarco extended to 22 points thanks to securing third place in Germany.

"I knew we were going to struggle, turns six and seven we were extremely slow," Quartararo, who had started the race from sixth position after a difficult qualifying session, said in his news conference.

"On other parts of the track we were okay, but this corner where we stayed a long time on the angle we struggled a lot.

"It was quite clear with the team this morning. We said that we had good pace, but to fight for the victory looks difficult.

"The goal was trying to finish in front of the Ducati and finish on the podium, so we achieved that."
