For a man more renowned for his attack, Knights superstar Kalyn Ponga has proved time and again that he can more than hold in his own defence.

In round 19, Ponga pulled off a classic tackle on Wests Tigers winger David Nofoaluma to walk away with Tackle of the Week honours with 42 percent of the vote.

Sharks rookie Briton Nikora grabbed the silver medal for Tackle of the Week with his bell ringer on Cowboys veteran Briton Nikora.

A couple of hard-hitting hookers, Brandon Smith and Cameron McInness, rounded out the finalists in Round 20.
