You'd have to have been living under a (sports world) rock not to be aware of it, but the most polarizing figure in pro sports had no idea.

Tim Tebow, who appears on the front of this week's edition of Sports Illustrated, was asked if he's worried about the legendary SI Cover Jinx. Tebow's response was ... notable.

"What is that?" Tebow asked San Diego reporters on a conference call, according to the North County Times. He added that he hadn't "heard" about it.

The Sports Illustrated Cover Jinx dooms featured individuals or teams to struggle. Everyone has a favorite SI Jinx story. Among my favorites: Cleveland Indians stars Joe Carter and Cory Snyder, who appeared on an April 1987 cover with the headline "Indian Uprising." The magazine predicted the Tribe as the American League's best team that season. Whoops. Cleveland went on to lose 101 games -- the worst mark in Major League Baseball.

Before the 1989 NFL Draft, SI previewed the top college players available, describing Michigan State tackle Tony Mandarich as the "best offensive line prospect ever." Three years later, SI featured Mandarich again, this time with the headline "The NFL's Incredible Bust"

Maybe Tebow doesn't know about the jinx because he's immune. While starring at the University of Florida, Tebow appeared on the cover of the popular magazine six times. And he did just fine at Florida.

Tebow, 24, did say he's heard of another, more modern football voodoo. "I heard of the Madden Jinx," the Heisman Trophy winner said.

The "Madden Curse" has taken down many NFL stars over the years, including Browns running back Peyton Hillis, who was on the cover this year and is now rumored to be headed out of town.

Tebow added, "I hope it (SI Jinx) doesn't happen. I didn't even know I was on that (cover)."

The Denver Broncos, with Tebow under center, will be in San Diego this weekend to battle Philip Rivers and the Chargers.
