The Rakuten Eagles announced today that they sold out of tickets to their game against the Nippon Ham Fighters on the 10th (there will be no same-day tickets). Assuming no rain outs and no changes to either starting rotations, that's the game could feature a match-up between Masahiro Tanaka and Yuki Saito.
Fuji TV is thinking about broadcasting the game if / when the match-up becomes official. And if they do broadcast the game, they'll also consider extending the time slot, if necessary (right now, they've tentatively set aside a 2-hour block beginning at 2pm). And even though their BS channel also has broadcast rights to the game, there's a good chance Fuji TV will only show the game on their non-BS channel (as a way to improve ratings).
UPDATE 9/8 @ 5:01pm - According to Sports Hochi, as of now, the game will be broadcast on NHK in 6 Tohoku prefectures, Fuji TV in Kanto and Hokkaido, and BS Fuji nationwide.
