Chris Byrd Bore Scores Against DaVarryl Williamson

America’s Chris Byrd retained his IBF heavyweight title with a unanimous points win over compatriot DaVarryl Williamson in Reno, Nevada.

The 35-year-old was rarely troubled by his former sparring partner but also failed to impress in a relatively dull affair.

Byrd eventually prevailed by scores of 115-113 and 116-112 twice to successfully defend his title for the fourth time.

The former WBO title holder became a two-time world champion when outpointing Evander Holyfield in December 2002.

All four of his subsequent defences have now gone the distance, following points wins over Fres Oquendo and Jameel McCline and a draw with Andrew Golota.
