Boxing star Sergey Kovalev was arrested for DUI in Los Angeles early Monday morning, TMZ Sports has learned.
The 36-year-old former light heavyweight champ -- who recently fought (and lost to) Canelo Alvarez -- was pulled over by the California Highway Patrol around 2 AM.
During the stop, the trooper believed Kovalev was under the influence and arrested him for DUI. He was taken to a nearby station where he was booked.
Records show Kovalev was released on his own recognizance around 7:35 AM.
It's not Kovalev's first brush with the law .
