Sebastien Vettel will replace Kubica in US GP

The doctors disagreed with Robert Kubica and disallowed him from competing in the US Grand Prix, giving newcomer Sebastien Vettel his chance for hisfirst ever Formula One race.

Formula One driver Robert Kubica came to Indianapolis Motor Speedway proclaiming he was alert, clear-minded and ready to race Sunday in the U.S. Grand Prix.

FIA, the international governing body of racing, ruled Kubica could not yet climb back into the cockpit four days after sustaining a concussion and spraining an ankle in a frightening crash at Montreal. He will be replaced by Germany's Sebastian Vettel, a test driver for BMW Sauber.

"I felt absolutely ready to race," Kubica said in a statement issued by the team after the doctors' decision. "I respect the decision. It was made because there is too much risk to let me race in this Grand Prix in case I have an impact so soon after Montreal. I will go home now."

Vettel, a 19-year-old rookie, is expected to make his first F1 start Sunday.

Rumour: Timo Glock to replace Ralf Schumacher

Looks like Ralf Schumacher will soon be joining his famous brother Michael Schumacher for skiing in Switzerland as he won't be having his job for long.

Despite denying rumours, the talk is that Toyota has already started looking for possible replacements for Ralf Schumacher and has even started talking to some of the prospects. The name which tops thw list of potential replacements is that of Timo Glock, former Champ Car World series driver. He is currently leading the points battle in the GP2 series in Europe.

The younger Schumacher is hoping to bounce back to at least earn his first point this season in Canada where he has had some of his best F-1 results with a win in 2001 and a second-place finish to Michael in 2003.

But if his practice time yesterday -- one minute, 19.331 seconds, which almost was three seconds off Fernando Alonso's pace and good enough for only 19th best on the day -- was any indication, it might be best for Schumacher to not book any hotel rooms beyond next week's USGP in Indianapolis.
