What happened: Allen checked in ahead of the Thursday night matchup listed as DETvsBUF. Kickoff is set for 8:15 p.m. ET.

Why it matters: The quarterback's arrival starts the final pregame stretch for one of the league's standalone windows. Early prime-time games put immediate focus on tempo, protection and late-week readiness once the ball is kicked.

What to watch: Inactive lists and the opening scripted possessions are the next checkpoints before kickoff. Thursday night will show how quickly the offense finds rhythm under the lights.
