Casey Stoner's withdraw from the next three rounds means the 2009 MotoGP World Championship has effectively become a two-rider contest between Fiat Yamaha team-mates Valentino Rossi and Jorge Lorenzo.

This weekend's Brno round will begin with Rossi 25 points (or one win) clear of Lorenzo, the difference between them almost doubling after both crashed from the lead of the British Grand Prix - leaving Lorenzo out on the sport, while Rossi rejoined to claim fifth.

The good news for the 22-year-old Spaniard is that the summer break gave him the chance to finally recover from his Laguna Seca injuries and he is 'excited' for the weekend ahead.

"I'm really excited about this race after what feels like a long time without one," said Lorenzo. "It was good to have a bit of a break and I used the time to work on my fitness and to completely recover from the injuries I had after Laguna, in the gym and with my physiotherapist.

"The result is that I feel much better than I did in Germany and England and I'm excited to be getting back on the bike. I like Brno and I have had good results in the past there, including three wins. This time my aim is to fight hard and get back on the podium," he declared.

"A little break to recharge the batteries has been useful for us all before the last seven races," added team manager Daniele Romagnoli. "This has given Jorge the chance to improve his fitness after his Laguna Seca injuries and he will be in good shape for Brno.

"All the team and Jorge want to forget the 'zero point' of Donington and we have a great motivation to catch Valentino at the top of the championship!

"From this grand prix the new engine rule will be applied but Yamaha has worked hard on engine durability and maintaining performance so we're confident that it won't be an issue," he stated.

Brno marks the first of seven rounds (and 175 points) before the end of the 2009 racing season.
