The results may not be much to shout about this year, but after their last lap battle at Indianapolis, Ducati knows its riders Nicky Hayden and Andrea Dovizioso still have plenty of fight.

Indy was the third time the team-mates had tangled on track, after incidents at Assen and Laguna Seca.

Home star Hayden emerged ahead on Sunday, after lunging for the inside at the final turn and clashing with eighth place Dovizioso - although both riders were overtaken by Bradley Smith after running wide and jumping over the kerb on the exit (see below for more pictures).

"After the race in Indianapolis, we know that our riders are both very motivated!" said Ducati team manager Vittoriano Guareschi, ahead of this weekend's Czech round.

"[Now] we go straight to Brno, a circuit that has quite a bit of elevation change and is similar to Mugello in some ways.

"Brno is a track that we know quite well, and it will be important for us to start working well immediately, beginning on Friday morning."

Dovizioso is seventh in the world championship and Hayden ninth. Dovizioso will remain with the team next season, when Hayden will be replaced by Cal Crutchlow.
