When does Showtime Championship Boxing return?

"Marvelous" Marvin Hagler defeated John "The Beast" Mugabi in an 11th-round knockout on the debut broadcast of Showtime Championship Boxing on March 10, 1986. A sister program, ShoBox: The New Generation, has occasionally aired on Friday nights, featuring fights between boxing prospects. With the announcement in October 2023 that Showtime Sports will be closing at the end of year, any future sports programming on the network will be branded under the CBS Sports branding.
