The Giants approached the NFL with accusations that the Steelers were using under-inflated balls in last week’s game, Fox Sports’ Jay Glazer reports.
The New York defense forced two turnovers during the 24–14 Pittsburgh win and tested the air pressure in the balls, Glazer reports. Both balls came in at below the required psi level. The Giants then sent the balls to the NFL, according to Glazer.
After the Patriots’ Deflategate controversy, the NFL began randomly testing the psi levels of footballs in the 2015 season, but those tests appear to be infrequent.
