Pittsburgh Steelers cornerback Justin Layne was arrested Friday ... after cops say he illegally had a loaded firearm in his car during a traffic stop in Ohio.
Officials for Willoughby Hills Police Dept. say Layne was pulled over at around 1:20 a.m. after an officer clocked him going 89 MPH in a 60 MPH zone in his 2020 Dodge Charger.
Police say during the stop, they discovered Layne had a suspended driver's license and a warrant for his arrest stemming from a failure to appear in court for a previous traffic violation.
Officers claim they also smelled an odor of marijuana in the car -- and after searching the vehicle, they say they found a loaded Glock 9mm pistol in the center console.
