Repsol Honda's Marc Marquez leads morning warm-up for the Japanese MotoGP, ahead of Ducati's Andrea Dovizioso and Maverick Vinales.

Aleix Espargaro completed a strong session for Suzuki in fourth, ahead of pole starter Valentino Rossi, who admitted on Saturday to being concerned about his race pace against the likes of Marquez.

Rossi's Yamaha team-mate Jorge Lorenzo, sore from his huge Saturday highside, completed the top six.

Dani Pedrosa fractured his right collarbone in a huge Friday practice highside and is replaced by HRC test rider Hiroshi Aoyama.

Andrea Iannone is missing his third race in a row following a back injury at Misano. His factory seat has been taken by Hector Barbera, with 2015 Australian SBK champion Mike Jones drafted in for a MotoGP debut at Avintia.

Bradley Smith and Jack Miller are returning from injury this weekend, while Yamaha test rider Katsuyuki Nakasuga is making his latest wild-card appearance.

Marquez has a slim mathematical chance of wrapping up the 2016 title today, should he raise his points lead from 52 to 76...
