This NFL player was cut for one of the most harmless reasons ever

Don't cross the boss.

When coach says something is his pet peeve, you better listen, or else you might end up like practice squad player Lawrence Okoye.

During a spot on Amazon and NFL's "All or Nothing" collaboration from the 2015-16 season, Arizona Cardinals head coach Bruce Arians mentioned he came to work two days in a row and someone was in his parking spot. He went on to note that if there's a sign in a spot, don't park there.

According to Sporting News, Arians canned Okoye and later told general manager Steve Keim the reason he cut him was over a parking spot:

"Parked in the wrong spot," Arians said to general manager Steve Keim and team president Michael Bidwill. "There weren't any parking places, so he just parked and came running in. Tough (expletive), bro."

Hopefully Okoye has learned his lesson, but a word to all Cardinals players — don't park in the wrong spot or you might not have a job moving forward.
