The reason behind that being, Lucic was arrested after facing some serious charges against his wife, in the end the charges were eventually dropped because his wife did not want to testify against him.
However, it's seems that this might all be false as Lucic still isn't eligible to return to the NHL because he entered into the NHLPA Players Assistance Program after his arrest, and only NHL Commissioner Gary Bettman is able to clear him, and allow him to return to the NHL.
