Just when we were actually thinking that the NFL's opening night of the preseason was unusually entertaining, comes this: The Steelers are under investigation for allegedly using a deflated football in the third quarter of Thursday night's 31-14 win over the Eagles.

The report comes from Howard Eskin on Twitter. The Eagles' sideline reporter for Sports radio 94 WIP in Philadelphia said the football in question was being used by Steelers rookie Mason Rudolph in the third quarter. When Eskin saw it on the sideline following an incompletion, it "looked like a marshmallow."

But NFL spokesman Michael Signora quickly put an end to the possibility of another Deflategate case opening via the following statement released on Twitter Friday morning:

"All footballs were in compliance with NFL rules following the pregame inspection process and all proper procedures were followed. In the 3Q, a football that was found to be defective was removed from play, will be sent back to Wilson for review.”

Of course, one might argue that the NFL going down another absurd rabbit hole over a deflated football would have qualified as entertaining. However, this investigation didn't last one full day, never mind spanning the 2014 divisional round until the opener of the '16 campaign, which began with Tom Brady ultimately serving a four-game suspension (in addition to paying a $1 million fine and the Patriots forfeiting two draft picks) and ended with New England securing its fifth Super Bowl under the current regime.
