KANSAS CITY, Missouri (AP) -- Sporting Kansas City CEO Rob Heineman says the loss of trust led the Major League Soccer team to sever ties with the cancer charity founded by Lance Armstrong.
Heineman also said Wednesday the "tumultuous environment" that developed before the cyclist admitted to using performance-enhancing drugs also played into the team's decision to change Livestrong Sporting Park to Sporting Park.
Heineman says the decision came after ESPN reported Livestrong said Sporting still owed the cancer charity $750,000 for 2012. Heineman says the team doesn't owe Livestrong any money.
Armstrong admitted to Oprah Winfrey this week he used performance-enhancing drugs during his cycling career.
Livestrong CFO Greg Lee says the organization doesn't discuss arrangements with its partners but he has "to ensure compliance by our corporate partners."
