Former world boxing champion and current boxing promoter Oscar De La Hoya announced that he has checked into a treatment facility and won't attend the Floyd Mayweather-Canelo Alvarez fight scheduled for Saturday night.

De La Hoya did not specify for what he is receiving treatment.

Golden Boy Promotions, of which De La Hoya is the president, was key to getting the fight set up -- a fight that could set records for pay-per-view buys.

"Canelo Alvarez and I have big fights coming up this weekend. His is in the ring and mine in treatment. I will not be at the fight this Saturday to cheer Canelo to victory since I have voluntarily admitted myself into a treatment facility," De La Hoya said in a statement. "I explained this to Canelo and he understood that my health and long-term recovery from my disease must come first. Thank you for your understanding. I ask for your support and privacy during this difficult time for me and my family."
