Tim Tebow won't be at the Republican National Convention after all.

The former football star was said to be among the biggest names at next week's GOP convention in Cleveland.

But he says in a Thursday night Facebook post that his attendance was simply a rumor. He commented roughly 12 hours after Donald Trump's campaign announced his status as a convention speaker.

Tebow says: "I just got back from the Philippines, and I wake up this morning to find out that I'm speaking at the Republican National Convention. It's amazing how fast rumors fly. And that's exactly what it is, a rumor."

Tebow, who won the Heisman Trophy in college while playing for the Florida Gators, says he'd do "anything for America." But that won't include appearing in Cleveland next week.

Tebow says he'll focus his time instead on helping children through his foundation.
