A report from Mass Live claims kicking balls used during the Kansas City Chiefs' win over the New England Patriots on Sunday weren't inflated properly, nearly nine years on from the scandal surrounding Bill Belichick and Tom Brady in 2015. The outlet reported that officials took balls meant for each team's kicking units into the locker room at Gillette Stadium at halftime last weekend to measure their weights following several complaints made. There, referees found out that the balls weighed 11 pounds per square inch. That's 1.5 pounds less than the NFL's minimum standard of 12.5 PSI. The maximum weight that a ball can be inflated to is 13.5 PSI. “They were all sitting around at 11 PSI. The threshold is usually 13.5,” an anonymous source told MassLive. “The Patriots told the refs they were a little underinflated or they felt that way. At halftime, they confirmed and obviously put air in them.” It's unclear specifically if the underinflated balls had penalized either team, as Chiefs kicker Harrison Butker and Patriots kicker Chad Ryland missed field goals in the first half.
