Valentino Rossi wi💦ll again be without crew chief Jerry Burgess at th✱is weekend's German MotoGP.

Burgess - the most successful crew chief in motorcycle grand prix history and at Rossi's side since his 2000 MotoGP debut - missed the recent Italian Grand Prix after 🌺returning to Australia to support his sick wife.

Burgess, who has won world titles with Rossi (7), Mick Doohan (5) and Wayne G𒐪ardner (1), was expected to💦 return for this weekend's Sachsenring event. However, that will not be possible.

"JB will watch this race on TV. The road 2 recovery 4 his wife has♛ got a bit longer, but still positive. He hopes 2 be in Laguna Seca," Rossi's mechanic, Alex Briggs, wrote o🅺n his Twitter page (@Alex__Briggs).

At Mugello, the role of Rossi's crew chief was filled by Max Bartolini, who normally works as the Ducati team's Technical Mana🐠ger.

Rossi finished sixth in front of his 🗹home fans and, although fourth in the world championship after eight rounds, he has only taken one podium finish.
