Canberra veteran Adam Mogg has announced that 2010 will be his final season in the NRL.

Mogg, currently sidelined with a knee injury, made the decision ahead of the Raiders' do-or-die finals match with Penrith on Saturday night.

Mogg admitted that the knee complaint which has plagued his season was a key factor in his decision.

"My body has decided to retire on me actually," he said.

"(The knee injury) was definitely the deciding factor.

"I've been pretty fortunate my whole career and it's just the last four months I've come across a knee injury.

"I've got two kids and I want to have a quality life after footy, it's important to me.

"I'd love to be able to play for another 20 years, but I'm really happy with my career."

The 33-year-old is still hopeful of forcing his way into the team this weekend despite missing the past two rounds through injury.

"It's the biggest game of the year, I'll try and do my best and be available for selection and if not this week, (then) definitely next week," he said.
