Devon Alexander's career undefeated streak was snapped on Jan. 29 by WBO junior welterweight champion Timothy “Desert Storm” Bradley at the Silverdome in Pontiac, Mich. After suffering numerous head butts throughout the contest, referee in charge halted the match in round 10 after consulting with the ringside physician. The judges favored Bradley 96-95, 97-93 and 98-93. Rather than opting to face a lesser opponent, Alexander has chosen a dangerous puncher in Matthysse, 28, from Chubut, Agrentina. Matthysse has a career knockout percentage over 92 percent with 26 of 28 victories coming by knockout.
Lucas Matthysse, in his most notable bout, Matthysse came within a whisker of knocking out five-time world champion Zab Judah in the 10th round on Nov. 6 at Prudential Center in Newark, N. J. Matthysse tagged Judah with a brutal right hand in the 10th round that sent Judah to the mat. Later in the round, Matthysse landed a left hook that staggered Judah again. Judah managed to escape the round and finish the fight—winning by the slimmest margin possible. One judge favored Matthysse 114-113, but the remaining two scorers favored Judah by a point, 114-113. Late January he faced former champion DeMarcus Corley and stopped him of the eighth round of a scheduled 12-round bout in Mendoza, Argentina. Matthysse put Corley down nine times – all but one time Corley taking a knee because of great pain – before the referee finally ended it. **
Evander Holyfield Vs Brian Nielsen. The World Boxing Federation, after consideration of all arguments, decided against sanctioning the proposed second title defence of its world heavyweight champion Evander Holyfield against Brian Nielsen. The main reason is that 46-year-old Nielsen has been out of the ring for almost a decade, thus does not qualify to contest a WBF world title.
The official weigh-in was held on Friday night in Denmark, with Holyfield at 225 pounds, while his opponent Nielsen, with his shorts on, weighed 238 pounds. It is to be noted that Nielsen had never been this light in his career. Neilson had said that although it would be mighty difficult for him to beat Holyfield, he promised it would not be one sided affair. Holyfield said that if he won he wwould move to next level and challenge for major titles.
Holyfield started the fight aggressively, pressing the 46-year-old Nielsen into the ropes and landing several hard jabs and hooks, knocking him down in the 3rd round. Despite getting a swollen eye in the 4th round, Nielsen kept on clowning to provoke Holyfield throughout the bout, prompting his trainer, Paul Duvill, to beg him to stop fooling around and focus on Holyfield. In round 10 Nielsen pushed a tired-looking Holyfield into the ropes with a series of combinations, before Holyfield turned it around. Holyfield pushed Nielsen into a corner and battered him with combinations until the referee stopped the contest.
It was a tough fight – he kept coming back, Holyfield said. He fought a very courageous fight. **
