NFL owners' decision to flex Thursday night games angers fans.

NFL owners have voted in favor of a scheduling mechanism that allows the league to flex into or out of "Thursday Night Football" games, but this could have a negative impact on fans who have already made travel plans and purchased tickets. The decision must be made no later than 28 days in advance of the game, and there's a maximum of two Thursday night games that can be flexed out of the five options. The NFLPA is not in favor of this, and Giants co-owner John Mara called the idea "abusive."
