Kurtis to miss Estoril.
Nobuatsu Aoki will be Proton Team KR's only representative at this weekend's Portuguese Grand Prix, following the news that Kurtis Roberts is still recovering from injuries sustained last time out at the Czech Republic Grand Prix.
Roberts suffered left elbow and wrist fractures in a wet-weather qualifying fall at Brno and, though he did not require surgery, it was decided late last week that he should remain in the USA to recuperate for the next round, the Japanese GP at Motegi, in two weeks time.

"It was too late to consider a replacement," said team manager Chuck Aksland.
Aprilia's Shane Byrne will also miss the event through injury, while Repsol Honda's Nicky Hayden remains doubtful after breaking his collarbone last weekend.
