Los Angeles Kings defenseman Slava Voynov was arrested Monday and suspended indefinitely by the NHL on suspicion of domestic violence against his purported girlfriend. The victim was beaten so badly in the alleged attack that she had to be rushed to a hospital, TMZ Sports reports.

“These concerns are of great concern to our organization,” the Kings said in a statement, according to ESPN. “We support the NHL’s decision to suspend Slava Voynov indefinitely during this process, and we will continue to take appropriate action as the legal proceedings and the investigation by the NHL take their course.”

The NHL’s collective-bargaining agreement allows league officials to suspend a player who is in the target of a criminal investigation. "The league may suspend the player pending the league’s formal review and disposition of the matter where the failure to suspend the player during this period would create a substantial risk of material harm to the legitimate interests and/or reputation of the league,” the NHL said in a statement.

Voynov accompanied the woman, who identified herself as his girlfriend, while she received medical attention and was arrested at the hospital, law enforcement sources told TMZ. He was arrested only after hospital workers called police to notify them of his possible involvement in the domestic violence incident.

The NHL veteran was released on $50,000 bail. His layer, Craig Renetzky, would not comment on details of the alleged incident, but said it was “very early” in the investigation, ESPN notes. Voynov is due back in a Torrance, California, court on Dec. 1.

“The court date is because he bailed out, not because any charges have been filed,” Renetzky told the Los Angeles Times. “At this point, there have been no charges filed against him. The police are still investigating, as we are, and we’re hopeful no charges will be filed.”

Voynov, 24, is in the midst of his fourth season with the Kings. He has two points through the first six games of the 2014-2015 NHL season. Voynov appeared in all 82 regular-season games for the Kings in 2013-2014.

His arrest comes after a rash of similar incidents led the NFL to institute new penalties related to players and employees who engage in domestic violence. The league plans to announce a revamped player conduct policy by Feb. 1, NFL Commissioner Roger Goodell said.
