What happened: The Jacksonville Jaguars opened their contest against the Philadelphia Eagles with a five-play possession that lost 23 yards. The sequence included a holding penalty, a fumble, and a delay of game infraction.

Why it matters: The disastrous start immediately put the offense behind schedule in a scoreless, in-progress game. Such execution errors often hand early momentum to the opposing defense.

What to watch: The Jaguars will need to clean up their pre-snap penalties and ball security on subsequent possessions to establish an offensive rhythm.
