Sauber's Sergio Perez - who suffered a nasty accident in Monaco two weeks ago - participated in the first Free Practice session in Canada today.
However, after FP1, the young Mexican reportedly started to feel unwell. Sauber's reserve driver, Esteban Gutierrez, wasn't even in Canada and therefore the team called upon the services of former driver Pedro de la Rosa.
The experienced Spaniard started the 2010 season driving for the Sauber team. However, after an indifferent start to the season, de la Rosa was replaced by Nick Heidfeld.
Pirelli then signed de la Rosa to test their new tyres, but at the end of the season, de la Rosa returned to his former employers McLaren as a test driver. Due to the short notice of his Sauber call-up, the Spaniard had to drive for the Swiss team in FP2 wearing his McLaren overalls!
Hopefully if he is required to replace Perez for the full weekend, Sauber will be able to find some overalls in his size.
