When the time comes, it may get joked about as another Thursday night snoozer to the national landscape, but don’t expect the Pittsburgh Steelers December 7 Thursday night game against the New England Patriots to be flexed. Mostly because it can’t.
Though it’s likely to be a low-scoring game between two lackluster offenses, NFL guidelines mandate that any Thursday Night Game be flexed at least 28 days in advance of the game.
From Pro Football Talk, who noted that in agreeing for Thursday night games to be flexed, there had to be extra advanced notice compared to normal flexing rules.
