Manning is a two-time New York Giants Super Bowl champion.
He put on a blonde wig, a fake nose, and a mustache as he embodied the phony personality of 26-year-old Chad Powers as he attended a walk-on tryout.
Manning wanted to see how far he could take the prank by ad-libbing about his backstory.
Manning turned heads when he started to pass the football.
He later revealed himself to the team and fellow walk-ons.
The video was shown on "Eli's Places," which airs on ESPN+.
