Donald Trump clashes with Joe Biden in Presidential MMA Grand Prix

Donald Trump and Joe Biden are set to clash in what one outlet is calling the saddest matchup of an imaginary MMA Grand Prix featuring every U.S. president.

Ahead of the UFC's historic White House card on Sunday, MMA Fighting has simulated a 45-president tournament bracket that divides commanders-in-chief into regions based on their years in office. Each fighter enters at the age and fitness level they held when assuming office, creating some brutal mismatches and a few legitimate scraps. "If there are going to be fights on the White House lawn, let's have some fights that fit the occasion," MMA Fighting's Jed Meshew wrote.

Play-in fights settle father-son rivalries and Muppet-named matchups

The opening rounds include John Adams defeating his son John Quincy Adams via fatherly whooping, with the elder Adams bringing farm-strong grit against his diplomatically softened offspring. James K. Polk gets past James Madison despite the latter being the Father of the Constitution, while Martin Van Buren overcomes a six-inch height disadvantage to stop John Tyler. The Greater Reconstruction Era sees Andrew Johnson edging Franklin Pierce, whose repeated wartime injuries prove too much to overcome, while Chester A. Arthur takes down Grover Cleveland in a battle of the tournament's most Muppet-named competitors.

John F. Kennedy emerges as a dark horse candidate, entering at just 43 years old with legitimate toughness earned swimming three miles while towing a crew member with his teeth after his Navy ship was destroyed. The second-youngest president stops Warren G. Harding, whose chest pains and shortness of breath leave him gassed early.

The full bracket and remaining matchups will determine which president leaves with the crown of Commander-in-Chief when UFC White House goes down Sunday on the South Lawn.
