Donald Trump has said he will break with tradition at this year’s Republican National Convention, promising to bring in many non-politician speakers.

The presumptive Republican nominee already has announced that his wife and children will speak at the convention, scheduled for July 18-21 at Quicken Loans Arena in Cleveland. Sports figures and business leaders are expected to be part of Trump’s speaker list, as well.

Matt Viser, a political reporter for The Boston Globe, indicated on Thursday that one of those sports figures would be Jack Nicklaus.

Apparently, though, that will not be the case. Scott Tolley, a vice president with the The Nicklaus Cos. and the World Golf Hall of Fame member’s longtime assistant, said Nicklaus will neither speak nor attend the Republican National Convention.

“Mr. Nicklaus is traveling internationally the next couple weeks, touching down in no fewer than six countries,” Tolley told Golfweek in an email. “So I can confidently confirm that (any) report (is) inaccurate and Mr. Nicklaus will not be attending any portion of the RNC.”

Tolley added that Trump’s representatives were “kind, respectful and highly professional” to reach out regarding whether Nicklaus would appear at the RNC, and have known for some time that travel obligations would preclude Nicklaus’ appearance in Cleveland.

Regardless, Nicklaus, 76, an 18-time major champion, has endorsed Trump. Nicklaus told CBS Sunday Morning in May that he certainly will vote for Trump if the billionaire property developer is on the GOP ballot and that, “He’s turning America upside-down. (He’s) awakening the country.”

Nicklaus has stumped for Republican politicians in the past, most notably Mitt Romney during the 2012 presidential race.

The Golden Bear’s name may be crossed off, but Trump announced at a rally Wednesday that Bobby Knight, the former Indiana basketball coach, will speak at the RNC. Legendary boxing promoter Don King is also expected to speak.
