The Los Angeles City Attorney formally issued the charge on Friday.
“We are aware the city attorney filed charges today against TJ McDonald stemming from his arrest in June,” the Rams said in a statement that misstated the month of his arrest. “As this is an ongoing legal matter, it would be inappropriate to comment further at this time.”
The 25-year-old McDonald has started all 38 games he’s played in his four seasons with the Rams, including Monday night’s loss to the 49ers. He would likely be suspended by the NFL if convicted of DUI.
