Less than two years into a six-year naming-rights deal for Livestrong Sporting Park, both the Livestrong Foundation and Major League Soccer's Sporting KC say the agreement is set to end for different reasons.

The move would be the latest of several by the anti-cancer charity to separate itself from its founder and former chairman, Lance Armstrong, who has been stripped of his seven Tour De France titles.

It also comes just two days before the first part of the disgraced cyclist's interview with Oprah Winfrey in which he admits to using performance-enhancing drugs was set to air.

The arrangement's initiation actually came from the Livestrong foundation, whose officials informed the team this week that the club had only paid $250,000 of the $1 million that it owed the foundation in 2012. Sources say the communication noted that failure to make the foundation whole within two weeks would result in the charity severing the deal.
