Patrick Peterson lost a contest, so he warmed up in a dinosaur costume

That T-Rex on the field is Patrick Peterson.

For some reason, Cardinals cornerback Patrick Peterson thinks he can hold his own in a throwing accuracy competition against Arizona’s quarterbacks. He can’t, and so he had to wear this before Monday’s game.

He could still get four or five interceptions a season in that thing.

The Cards like to play a game called “Chuck It To The Bucket.” The competition was featured on the team’s recent Amazon series, where Carson Palmer revealed that Peterson usually loses.

He doesn’t lose every time, though. Palmer had to wear a marshmallow costume last month.
