As noted earlier, the MLB Playoff game between the St. Louis Cardinals could affect AEW Dynamite on TNT.
The St. Louis Cardinals vs. Atlanta Braves game is currently airing on TBS. That is followed by the Washington Nationals vs. Los Angeles Dodgers at 8:30 pm eastern on TBS.
However, if the Cardinals/Braves game (TBS) does not end before 8:30 pm eastern then the second game (Nationals/Dodgers) will be moved to TNT. That would directly affect AEW Dynamite.
The plan, according to the truTV schedule on their website and the TNT website schedule, is for AEW to air on both TNT and truTV at the same time from 8 to 10 pm.
If the first baseball game goes long then a portion of AEW Dynamite (on TNT) will be interrupted until the game ends. TNT will return to airing Dynamite as soon as the Cardinals/Braves game ends and Nationals/Dodgers will move to TBS. If the Cardinals/Braves ends before 8:30 pm eastern then you have the option of watching the entire 2 hours Dynamite on TNT or truTV. Either way, the entire 2 hours will air on uninterrupted on truTV starting at 8 pm eastern.
A 2-hour replay will air at 10 pm eastern on TNT.
