Muhammad Ali-George Foreman (1974) -- In ''The Rumble in the Jungle'', Ali employed the ''Rope-A-Dope'' and knocked out Foreman in the eighth round.


Marvin Hagler-Thomas Hearns (1985) -- Short, but exciting fight, featuring non-stop action. Hearns broke his hand and Hagler had a gash on his forehead. After both were checked out, Hagler came out and used a flurry to win by TKO in the third.


Buster Douglas-Mike Tyson (1990) -- Douglas, a 42-to-1 underdog, was knocked down late in the eighth round, but got up at the count of nine. Douglas then proceeded to KO the thought-to-be-invincible Tyson with a combination in the 10th round.


George Foreman-Michael Moorer (1994) -- At age 45 and trailing on all three scorecards, Foreman looked like he was finished. But he rallied to become the oldest to win the heavyweight title with a 10th-round knockout.


Diego Corrales-Jose Luis Castillo I (2005) -- In what is considered a classic fight, Corrales was knocked down twice in the 10th round, only to rally for a TKO later in the round.


But my favorites.

Kostya Tszyu - Zab Judah in the infamous "Queer street dance/shuffle.

Samuel Peter - Jeremy Williams

Shcew Powell - Cornelius Bundrage. Another queer street moment.

I am sure I can think of more but me tired. These can not be compared to the impossibles I picked on ESPN. All long shots and the underdogs won. Those were some upsets. Minus the corrales mouth piece contraversy but it was smart and bought him the time he needed to do something he will never be able to do again.
