What happened: The NFL will let head coaches designate another sideline staffer to initiate replay reviews starting this season. Zac Taylor said officials routinely asked who had Cincinnati's flag before games and allowed the arrangement without issue.

Why it matters: Cincinnati no longer depends on officials informally tolerating its sideline setup. The procedural cleanup comes before Thursday's preseason opener against Detroit.

What to watch: The Bengals host the Lions at 7 p.m. Thursday. Joe Burrow, Ja'Marr Chase and Tee Higgins are expected to take the field.
