Brandon Aiyuk‘s a speed demon on the gridiron … but, he had to go very slow earlier this week — ’cause a cop pulled him over in a new car thinking he may have stolen it.

Here’s the deal … Aiyuk recently purchased a Jeep Grand Cherokee Trackhawk — an SUV valued at around $90K. He drove it straight off the truck, and he says within two miles a cop pulled him over.

Aiyuk filmed his chat with the cop … who mentions the wide receiver was cited for driving unregistered Dodge Chargers in California — cars the officer says are routinely a target for thieves.

Aiyuk asks why and the officer replies that he “doesn’t watch football” — which BA points shouldn’t matter since none of the cars showed any indication they were stolen.

It’s a tense exchange … though later on in the clip Aiyuk defuses the situation — asking the cops if he wants to see what’s under the hood and revving the engine for the officer before he takes off.

Worth noting … the license plate on the car actually reads “Stole It” — presumably a marketing push by the dealership to show the driver got such a good deal it’s like they stole it.

Most master criminals don’t advertise their crimes like that … but, maybe the officer thought a “Scooby-Doo” character was committing a crime here.

If you don’t know … Aiyuk’s got enough cash to buy a whole fleet of new cars if he wants — he signed a four-year deal worth $120 million before last season. So, he’s got money to burn.
