Dwayne Bowe was arrested Sunday night in Riverside for speeding and possession of a controlled substance.
Riverside police pulled Bowe over for driving 48 miles per hour in a 35 mph zone, and found more than ten grams of marijuana in a bag. An additional 4.2 grams were in a passenger's backpack.
It's unclear if the wide receiver will face a suspension as early as this Sunday when the Chiefs play the one-loss Broncos Sunday night in Denver.
Bowe was suspended for four games in 2009 when he violated the league's performance-enhancing drugs policy.
Bowe signed a five-year, $56 million contract in the offseason. He has 33 catches for 369 yards and two touchdowns in 2013.
