Rosen posted photos of the damaged car Sunday on Instagram. The "minor" accident occurred on Saturday in Los Angeles, according to the Cardinals.
"I'm okay ... but," Rosen wrote for the caption on one of the photos, including a crying emoji.
He later joked about the accident, posting a photo of himself pretending to punch the side of the car.
"Dude, I'm telling you the NFL doesn't test for this stuff," Rosen wrote for the caption on that photo.
