A Fox bid for WWE television rights could be the biggest TV sports agreement since the network poached rights to “Thursday Night Football.” Fox Sports is now poised to steal away TV ratings giants “Raw” and “SmackDown Live” from their longtime home at the the USA Network. An agreement would probably result in WWE flagship show “Raw” airing Mondays on Fox’s broadcast network, while its Tuesday sister series “SmackDown Live” would stay on cable with a move to FS1.
