The Russian-born American billionaire's Access Industries already holds a 3% stake in the sports broadcaster, and has a controlling stake in terrestrial pay TV company Top Up TV.
According to BBC News, it is hoped that Blavatnik's offer - which arrived at Setanta within the last 48 hours - will buy the company time to avoid going into administration.
Setanta has defaulted on a £3m payment to the SPL and must make a £30m payment to the Premier League by Monday. It is not currently accepting new subscribers.
