Devon Alexander added the IBF junior welterweight title to his collection while retaining his WBC belt with an eighth-round KO of Juan Urango Saturday night. Alexander improved to 20-0 while scoring his 13th KO to unify the belts.

Alexander was winning a competitive contest with his speed and movement when he suddenly broke open the fight with an uppercut that floored Urango in the eighth. Urango (22-3-1, 17 KO's) got up, bleeding from the nose, but had nowhere to go as Alexander went in for the finish.

A combination from Alexander put Urango down again moments later. The IBF champion beat the count but the referee waved off the bout at the 1:12 mark of round eight.
