WASHINGTON -- Republican presidential candidate Donald Trump says he doesn't like going up against NFL games when he debates Democratic opponent Hillary Clinton this fall.

Trump also says the league complained to him about the debate schedule in a letter.

A spokesman for the NFL, however, said the league did not send a letter to the billionaire businessman.

The independent, nonpartisan Commission on Presidential Debates serves as the debate sponsor and sets the participation criteria, dates, sites and formats. The sites and dates for the 2016 debates were announced in September 2015.

The commission "did not consult with any political parties or campaigns in making these decisions," according to a statement issued Saturday.

In an interview with ABC's Sunday show "This Week," Trump was asked if he would accept the commission's schedule.

He replied: "Well, I'll tell you what I don't like. It's against two NFL games. I got a letter from the NFL saying, 'This is ridiculous. Why are the debates against -- 'cause the NFL doesn't wanna go against the debates. 'Cause the debates are gonna be pretty massive, from what I understand, OK?"

Asked about Trump's assertion, NFL spokesman Brian McCarthy tweeted: "While we'd obviously wish the Debate Commission could find another night, we did not send a letter to Mr Trump."

Two of the three debates scheduled in September and October will be televised during NFL games. On Sept. 26, the night of the first debate, ESPN will carry the Monday night game featuring the Atlanta Falcons and New Orleans Saints. On Oct. 9, the second debate will air opposite the Sunday night game featuring the Tampa Bay Buccaneers and Carolina Panthers on NBC.

"I don't know how the dates were picked. I don't know why those particular dates," Trump told ABC.

Trump did say three debates were "fine" and that he'd rather have three than one.
