Blake Grupe is an undrafted rookie football player for the Saints who, at 5-foot-7 and 156 pounds, looks nothing like an American football player. Even laughing at the matter when the stadium security tried to prevent him from entering the stadium before the game, then tried to remove him from the players’ area in the stadium after he kicked the game-winning field goal, and he took a shower and changed.

Grupe explained his night’s fun on Twitter, saying that security told him he needed credentials for warm-ups before the game (sidelines need credentials, but players don’t), and then after he kicked the second-last field goal that won the game for the Saints, Security again tried to get him away from the players’ area only after he took off his uniform.

“Step 1: I question you walking the field for lack of credentials,” Grupe wrote on his 3,000-follower Twitter account. “Step 2: Hitting a game winner. Step 3: Stop the security thought I was a fan when trying to get a player out. Stay humble. Thankful. Great team win!”

Grupe is a long shot at making it to the Saints roster in his rivalry with Wil Lutz, but he’s currently an NFL player. Even if he had to convince people to believe him.
