Tyson Frizell has re-signed with St George Illawarra for four more NRL seasons.

The Dragons announced on Sunday the NSW forward had re-committed to the club until the end of the 2020 season.

“”It was a pretty easy decision for me as a local junior,” Frizell said.

“It’s been a bit of a rollercoaster the past year but hopefully the club is moving forward and I want to be a part of that.”

The signing caps off a good week for the Dragons who also secured the signature of hooker Cameron McInnes from South Sydney on a two-year deal.
