Stephen Espinoza, executive vice president of Showtime Sports, on Wednesday urged boxing fans to tune into the top of the CBS college football broadcast Saturday at 12:30 p.m. (PT) for a surprise.

Showtime is televising Saturday’s Floyd Mayweather Jr.-Saul “Canelo” Alvarez junior middleweight title fight from MGM Grand in Las Vegas on its pay-per-view arm.

“Be sure not to be late,” Espinoza said at the final news conference for the fight.

Showtime is owned by CBS.
