The Cosmopolitan of Las Vegas filed a lawsuit against the winger Monday alleging that he failed to pay back $500,000 in casino markers that were given to him in April.
Evander Kane has been slapped with a monster lawsuit over alleged gambling debts.
The San Jose forward's stick made contact with lineman Kiel Murchison while slashing Vegas's Deryk Engelland.
Kane reportedly took out eight separate credits totaling $500,000 in mid-April, during the Sharks' playoff series with the Las Vegas Golden Knights.
Kane, in the second year of a seven-year, $49 million contract, lost around $112,000 in salary this season after he was suspended three games for abusing an official during a pre-season game.
As well as the sum of $500,000, the Cosmopolitan is also seeking the payment of legal fees from the National Football League player. They also declined to comment on pending litigation, citing company policy.
The two players have kept their long-standing rivalry going into this season, one that began with Kane being ejected for an altercation with a referee in the team's preseason finale against the Knights in Las Vegas.
No comments were made on the allegations by Kane, the San Jose Sharks, or the National Hockey League to date.
