Joseph Parker vs Solomon Haumono highlights

Unbeaten New Zealand heavyweight Joseph Parker has made it 20 professional wins in resounding fashion, beating Australian Solomon Haumono by knockout in Christchurch.
Parker floored the 40-year-old former rugby league international on Thursday with an upper-cut midway through the fourth round. Dominating the earlier rounds, Parker remains the mandatory challenger to Briton Anthony Joshua's IBF belt.
Haumono would have taken that status from him but was never in the contest, looking increasingly vulnerable against Parker's superior speed through the first three of 12 scheduled rounds.
The fight ended when heavy favourite Parker followed a left jab with a right upper cut which sent his Auckland-born opponent to the canvas.
