This came after a review of the case Wednesday by the district attorney's office, according to Redondo Beach police Lt. Joe Hoffman.
Voynov was arrested early Monday morning after an alleged domestic violence incident in Redondo Beach. A court date of Dec. 1 has been set, and Hoffman said the district attorney's office will receive the additional information before that date.
"Upon completion of the case review, the district attorney's office requested additional follow-up before making a determination on the filing of charges related to this investigation," Hoffman said.
Voynov's attorney, Craig Renetzky, told The Times he saw this as a "positive sign that they didn't file" charges.
"It'll give me some more opportunity to present some of our investigative results," he said.
Voynov has been suspended by the NHL indefinitely and continues to be paid. He was arrested and released on $50,000 bail on Monday morning and was immediately suspended by the NHL.
Thursday's game against the Buffalo Sabres is the first one Voynov will miss. Renetzky described his client's situation as " living in purgatory." NHL deputy commissioner Bill Daly said Wednesday's announcement would bring "no change" to Voynov's indefinite suspension.
Renetzky said he interviewed Voynov and the woman he allegedly injured using a Russian interpreter.
"She was very clear he did not punch her, he did not hit her in that way," Renetzky said. "Based on what she is telling me, there's no crime here. There's certainly not enough to bring criminal charges."
Renetzky would not specify the injuries the woman suffered but said they resulted from an accident. He said the "misunderstanding" with police could have occurred because of language issues.
"I don't think they understand what occurred," he said. "We're going to try to present some exonerating evidence hopefully in the next few days. I'm hoping the league will reconsider their position."

Etc.: The Kings received good news in regard to defenseman Jake Muzzin, who has been out since training camp because of an upper-body injury. He was cleared to return and will make his season debut tonight, saying: "It's not 100% but it's good to go." There are two other decent story lines: Kings forward Jordan Nolan will play against a team coached by his father, Ted Nolan, a first for Jordan in the NHL. And Kings defenseman Brayden McNabb played parts of two seasons for the Sabres.
