Bruno Senna will not drive for HRT next season according to team principal Colin Kolles.

Last year Senna raced at all but one grand prix for HRT as Karun Chandhok, Christian Klien and Sakon Yamamoto were rotated in the second seat throughout the season. However, Kolles made clear that Senna's chances of returning in 2011 are zero.

"I can definitely say that Mr Bruno Senna is not going to race for HRT, 100% not," he told Reuters.

On Thursday HRT signed 33-year-old Narain Karthikeyan, who comes to the team with backing from Indian car giant Tata. Kolles added that he is in talks with "a few drivers" about partnering Karthikeyan, including Klien, Yamamoto and others.

Aside from the second HRT drive, Force India is the only team with seats still available on the 2011 grid. Adrian Sutil and Paul di Resta are widely tipped for the positions, although Tonio Liuzzi still has a contract with the team and is adamant he will stay.

As a result the chances of Senna staying in F1 for a second year are incredibly slim, leaving the nephew of the great Ayrton Senna facing a repeat of 2009 when he failed to land a drive in single seater racing.
