Pedro de la Rosa will take Sergio Perez’s place at Sauber for the rest of the Canadian Grand Prix weekend.
Perez was passed fit to race yesterday, following his crash in Monaco. But he reported he was feeling unwell after the first practice session this morning.
He said: “Of course I wanted to drive and I had no doubt I was alright. But apparently this is unfortunately not the case.
“I am deeply disappointed. I spoke to the team after the session and told them that I?óÔé¼Ôäóm not a hundred per cent fit. I only want to drive when I?óÔé¼Ôäóm a hundred per cent well. I need some more time to recover.”
Team principal Peter Sauber said: “This development hit us by surprise, because Sergio underwent thorough medical checks, first in the hospital in Monaco, then in a hospital in Z?â??rich, and finally, the FIA doctors gave him the green light this Thursday in Montreal.
“Nobody could have foreseen that he would feel unwell. Maybe we are being overly cautious, but when it?óÔé¼Ôäós about the health of our drivers we take zero risks.”
De la Rosa started 14 races for Sauber last year before being replaced by Nick Heidfeld.
He is one of McLaren’s test and reserve drivers.
