What happened: NFL official Don Willard will make league history Sunday by working two games on the same day. Willard is scheduled to referee the Indianapolis Colts' matchup against the Miami Dolphins at 1 p.m. ET. Following that game, he will travel 109 miles to Cincinnati to officiate the Sunday Night Football contest between the Pittsburgh Steelers and Cincinnati Bengals.

Why it matters: The unprecedented assignment comes after nationwide air travel disruptions and FAA ground stops forced the league to reassign officiating crews across Week 10. The schedule leaves Willard with a tight turnaround between the afternoon finish in Indianapolis and the 8:20 p.m. kickoff in Cincinnati.

What to watch: Willard takes the field first in Indianapolis at 1 p.m. ET before traveling for Sunday night's 8:20 p.m. ET kickoff in Cincinnati.
