Coliseum Sports Media look set to expand their content after securing some European rugby rights previously screened by Sky TV.
The move follows the loss of English Premier League football and top golf from Sky's repertoire.
But Sky are still tipped to hold on to Rugby World Cup rights for New Zealand and on Friday announced the signing of a conditional five-year deal with the New Zealand Rugby Union and Sanzar, which included the screening of All Blacks and Super Rugby matches. A long-form agreement will follow.
Coliseum Sports Media are set to announce on Tuesday they have secured rights to screen some European rugby on their live online service.
Chief executive Tim Martin would not divulge the nature of the competition, saying all would be revealed on Tuesday.
