Registered users of CBS SportsLine Fantasy Football can now manage their leagues and track players through the CBS SportsLine Fantasy Football Companion, a new application they can access only through a broadband-enabled TiVo Inc. Series2 DVR.

The application, a joint effort of TiVo and CBS SportsLine, also provides hooks for advertisers, which TiVo is calling “sponsors.”

The application includes a number of features interesting to fantasy football spuds, including the ability to check live player and team scores on all league matchups; get up-to-the-minute details and statistics on the current week’s matchups; monitor weekly changes to league standings throughout the season; view active and reserve players, injury status, and make late changes as needed; read breaking headlines and player news that impact a team’s lineup; and watch short-form CBS SportsLine videos, including pre-game analysis, player interviews and special fantasy football content.

Not entirely coincidentally, DirecTV also has an application that targets fantasy football participants (see story).
