HRT had earlier confirmed that Narain Karthikeyan would be racing for them in 2011. The announcement would also mean that either Sakon Yamamoto or Christian Klien need to look elsewhere. HRT are probably looking for experienced drivers this season, unlike like last year where they started with two rookie drivers.
With the 2011 grid now clearer, the only available race seats are one at HRT and one at Force India.
