Richards had his contract terminated by the Kings on Monday after he was allegedly stopped by police June 17 and questioned about illegal presciption drugs near a Canadian border crossing, according to a report from TMZ Sports. Richards reportedly wasn't charged with a crime during the police stop, but was asked about the prescription painkiller Oxycodone. It's not clear from the report if Richards was even carrying the drug in question at the time, though the Kings evidently determined from the evidence that the incident represented a "material breach" of the forward's contract with the team. The Kings were thought to be pursuing a buyout of the remainder of Richards' 12-year, $69 million contract, so the timing of the report will likely lead the NHLPA to investigate the situation closely. Regardless of the outcome, Richards is officially an unrestricted free agent and will be free to sign with any team.
