WBC Featherweight Title

How it went..
"Bobby Chacon retained his WBC featherweight championship Saturday night in lightning-like fashion, knocking out Mexico's Jesus "Papelero" Estrada in the 2nd round of their scheduled 15 round title fight. Chacon knocked down Estrada twice in the 2nd round and referee John Thomas didn't even bother to count the second time. Thomas signaled the end after Estrada went down from a barrage of Chacon rights and lefts near a neutral corner with only 34 seconds remaining in the round. Chacon had his opponent down the first time on a vicious right hand to the head after the fighters had exchanged punches in Chacon's corner." - United Press International
