Phillies outfielder Odubel Herrera has been placed on leave under MLB’s domestic abuse policy after police arrested him Monday night.

Herrera was involved in an incident at the Golden Nugget Hotel and Casino in Atlantic City, according to NBC Sports Philadelphia. The incident involved his 20-year-old girlfriend, who “had visible signs of injury to her arms and neck that was sustained after being assaulted by her boyfriend, David Odubel Herrera, during a dispute,” according to the police report.

Herrera was reportedly released from custody.

“This morning we were made aware of an alleged incident involving Odubel Herrera,” the Phillies said in a statement. “Upon receiving this information, we immediately reported the incident to Major League Baseball, which has informed us that Herrera has been placed on Administrative Leave. The Phillies take any domestic violence accusation seriously, and strongly support the Joint Domestic Violence Policy agreed upon by MLB and the MLBPA.”

Next to Bryce Harper and Andrew McCutchen in the Phillies’ outfield, Herrera has had a disappointing start to his season, hitting .222 with a .629 OPS.
