CSB - David Nyika - Boxing

American gatekeeper Tommy Karpency has stepped in at late notice to challenge Kiwi boxer David Nyika after his original opponent failed a drugs test.

Karpency will fight Nyika, the Olympic bronze medallist and 9-0 cruiserweight in the pro ranks, in the main event at Auckland’s Viaduct Events Centre on September 14 after it emerged veteran Australian Blake Caparello failed a VADA test for elevated testosterone, forcing a change 10 days out from the fight.
