The late Muhammad Ali will be remembered with multiple TV tributes fast-tracked for Saturday night.

ABC’s 20/20, which was originally set to encore a September broadcast about O.J. Simpson, instead will air at 8/7c the new special “Muhammad Ali: The Greatest of All Time,” taking stock of reactions from around the world to the former heavyweight boxing champion’s passing.

Similarly, CBS at 9 pm will present the 48 Hours special “Muhammad Ali: Remembering a Legend.”

Ali lost his 30-year fight with Parkinson’s syndrome on Friday, at age 74, after being hospitalized with respiratory issues. (Read full obituary here.)

Spike meanwhile will at 9 pm encore the 2009 documentary Facing Ali, in which 10 of the fighter’s acclaimed rivals pay tribute to “The Greatest.”

TVLine will share/tweet updates to this list as other programming is announced.
