What happened: Atlanta Falcons quarterback Michael Penix Jr. stated he does not know the reason offensive coordinator Tommy Rees transitioned down to the sideline. Penix added that Rees operating from the field rather than the coaches' booth does not necessarily make a difference for him.

Why it matters: Atlanta has lost two straight games as the offense looks to stabilize midway through the season. Penix previously credited Rees for an in-game reset following an interception earlier in the year. Moving a primary play-caller to the sideline is typically aimed at streamlining real-time communication between drives.

What to watch: The Falcons return to action Sunday against the Kansas City Chiefs with kickoff set for 1 p.m. ET.
