Celtic to start with Ross County test
Scottish Premier League champions Celtic will open their title defence with a home fixture against Ross County on August 3.
The International Automobile Federation has opened a spot on the 2013 calendar for another European event.
Reports earlier in the year suggested the return of a French Grand Prix after a five-year hiatus was in the offing but it now appears the most likely addition will be the return of the Turkish Grand Prix at a revamped Istanbul Park.
