A champ was ruined by manager in over the weight non title fight ?

I won a title, had HOF possibilities, but was absolutely ruined by my
famous manager who matched me up with a 10 pound heavier
murderous puncher, injuring me severely, ending my career at young age.
Who am I ?

 

Al, yes Marty Servo who was a tough cookie and great WW prospect who gave the 5"inch taller Ray Robinson sensation, fits in 2 close bouts. Servo ko'd Freddie Red Cochrane for the WW title in 1946. He was going great
guns, but his famous manager foolishly matched Servo with the new
sensation Rocky Graziano ,who one year before flattened a great prospect Billy Arnold an 8-1 favorite at MSG, ruining Billy Arnold forever. So the
10 pound lighter Servo was pulverized by Graziano who damaged Servo's
nose, ruining his future career also. The manager of Marty Servo was none other than Al Weil who later on guided Rocky Marciano to a HW title.
The early Rocky Graziano [pre Zale] was a terror in the ring against welterweights...:good
