Former EBU heavyweight champ and world title contender Karl Mildenberger has passed away at the age of 80, reports media in Germany. 

Mildenberger was a capable boxer and his southpaw style gave Ali plenty of problems but eventually the Greatest won on a 12th round TKO.

Mildenberger remained a force in Europe but lost to Leotis Martin in the WBA tournament to determine a new champ after Ali had been stripped of the belt.  Karl lost to Henry Cooper in his last fight and retired with a record of 53-6-3.

Mildenberger worked until his retirement in 2002 as a lifeguard and retired from the public eye when he turned 70 years old.
