Ducati's World Superbike champion Troy Bayliss will make a one-off return to MotoGP in place of Sete Gibernau at the Valencia Grand Prix.
Bayliss spent three years in MotoGP with Ducati and Honda
Former MotoGP rider Bayliss, who won the WSB title for Ducati Xerox, will deputise for the injured Spaniard on 29 October, the last race of the season.
"I have this great opportunity and it'll be great to meet up with some of my old team and mechanics," he said.
"I do feel sorry for Sete, though, as he who won't be racing in his home GP."
Gibernau's season never really recovered from the broken collarbone he suffered in the Catalunya Grand Prix in June.
Missing the last race of the season means Gibernau has had his last MotoGP ride for Ducati, as it was announced that next season his place on the team would be going to Casey Stoner.
The race in Valencia will see Valentino Rossi and Nicky Hayden going head to head for the world title.
