Organisers of tomorrow's Indianapolis MotoGP have said they may well sacrifice the 250cc and 125cc classes and bring the main event forward if rain threatens the race.
It is not known as yet when the rain is going to turn at Indianapolis tomorrow, but the weather forecast says it is coming. The MotoGP safety commission will reschedule MotoGP around the rain and the support classes may well not run.
