The power-packed left hand of Ghanaian Joshua Clottey sent Anthony Mundine to the canvas five times and put serious doubts over the Australian boxer’s future at Newcastle Entertainment Centre last night.

Clottey outclassed the former rugby league star in a unanimous points decision – 116-108, 115-109, 117-108.

It was Mundine’s sixth loss in 52 fights and first in Newcastle in four bouts.

Mundine was floored in the third, twice in the sixth then again in the eighth and 10th, each time with Clottey’s left hand providing the telling blow.
