Philadelphia Flyers forward Trevor Zegras was penalised for delay of game during a preseason match against the Boston Bruins for tucking the back of his jersey into his trousers whilst taking a faceoff. The incident has drawn widespread criticism as an absurdly strict application of equipment regulations, despite Zegras receiving a prior warning in accordance with rulebook procedure. The penalty highlights the National Hockey League's renewed enforcement push on proper equipment wearing, announced to teams several weeks earlier.

The infraction is part of a broader crackdown covering visors, neck guards, and jerseys that the league had communicated to clubs beforehand. Head coach Rick Tocchet confirmed the advance notice but acknowledged the rule was rarely enforced previously, making the sudden strict application feel disproportionate. A second such violation would have resulted in a game misconduct; the league is applying this enforcement to the preseason before the regular season begins.
