RingTV.com has a live round-by-round update of tonight's light heavyweight championship during which RING/WBC titleholder Adonis Stevenson scored knockdowns in the first and fifth rounds and rose from the canvas himself in the ninth of a unanimous decision over Andrzej Fonfara at Bell Centre in Montreal, Quebec on Showtime.

Stevenson (24-1, 20 knockouts), a 36-year-old southpaw, took a run of 13-1 with 13 knockouts in his previous 14 fights into the bout with Fonfara (25-3, 15 KOs). Stevesnon had stopped 10 consecutive opponents since being knocked out by Darnell Boone in April 2010.

Stevenson had an advantage in overall punches landed, 329-to-217, as well as in power shots (260-to-157) and jabs (69-to-60),

Fonfara, 26, brought a run of 15 straight victories, 12 by knockout, into the clash and was last in action during December's second-round knockout of Samuel Miller that followed a ninth-round stoppage of ex-beltholder Gabriel Campillo in August.

Fonfara had last suffered defeat against Derrick Findley by second-round stoppage in July 2008 but did not blink during Friday's nose-to-nose post-weigh-in staredown with Stevenson, whom he vowed would get knocked out for the second time in his career.

In victory over Fonfara, Stevenson hopes to have set up a potential showdown with 49-year-old Bernard Hopkins, who was in action last month with a majority decision victory over Beibut Shumenov, unifying the IBF and WBA belts.

The Showtime broadcast began at 9 p.m. ET/PT.
