Under-Inflated Footballs Mar Patriots-Chiefs Game

Patriots' Coach Bill Belichick calls for NFL explanation after both teams struggle with under-inflated balls.

During the Patriots' 27-17 loss to the Chiefs, the kicking footballs were found to be under-inflated by over 2 psi, significantly below the regulation 13.5 psi.
Patriots' head coach Bill Belichick confirmed the issue, stating that both teams had problems with how the ball was traveling on kickoffs, punts, and field goals.
Both Patriots' kicker Chad Ryland and Chiefs' kicker Harrison Butker missed a field goal in the first half, which Belichick attributed to the under-inflation.
Belichick deferred to the NFL for an explanation, as the league is in control of ensuring the balls are inflated to the proper range of 12.5-13.5 psi before each game.
The NFL has yet to comment on the issue.
