Senna to drive some IndyCar races?

The IndyCar Series lost one high-profile Brazilian with an F1 pedigree in the offseason with Rubens Barrichello switching to his domestic stock car series, but Bruno Senna, nephew of his mentor Ayrton Senna, could be in the frame to fill that void with a part-time drive on road and street courses. Senna, who lost his seat at the Williams F1 team for 2013, recently signed to drive for the Aston Martin Racing GTE team in the FIA World Endurance Championship, but could be on the IndyCar entry list on a few non-conflicting weekends. speedtv.com
