The former King’s Casino owner is reportedly in very grave condition
Leon Tsoukernik, a well-known poker figure and former King’s Casino owner, is reportedly in critical condition after being found unresponsive at his home in the Czech Republic. Emergency services responded to the scene, suspecting a possible overdose of propofol, a powerful sedative typically used in medical procedures. Local media reports suggest the drug may have been administered improperly, but details remain unclear.
Tsoukernik, the former owner of King’s Resort and a professional poker player, was transported by air ambulance after two medical crews and a doctor attended to him. A police spokesperson confirmed an ongoing investigation into potential illegal activity or serious bodily harm. Authorities are examining all circumstances surrounding the incident but have not named any suspects.
Tsoukernik sold his stake in King’s Resort last year, reportedly earning €400 million (US$412 million) from the transaction. Known for hosting high-stakes poker tournaments, the casino helped elevate his profile in the gaming world.
As a player, Tsoukernik has amassed nearly $5.5 million in live tournament earnings. His most notable wins include a $1.2 million prize from a 2019 WSOP Europe event at King’s Resort and a $1.8 million payout from a fourth-place finish in the 2017 Super High Roller Bowl.
Propofol, the drug implicated in this case, requires a prescription and careful administration due to its potent effects. While primarily used as an anesthetic, it has been associated with recreational misuse and fatal overdoses, including the death of Michael Jackson in 2009. Such cases underscore the drug’s risks when used outside a medical setting.
Tsoukernik remains hospitalized, with local authorities continuing their inquiry into the incident. His contributions to poker and the casino industry have made him a notable figure, and the news of his condition has drawn significant attention.
