The 27-year-old has played 88 NRL games since making his debut for Newcastle in 2010 – playing three seasons at the Knights before moving to the Canberra Raiders in 2013.
The back rower has signed on with Wests Tigers until the end of 2017 and will further strengthen the depth of talent amongst the first grade squad.
After three seasons with the Raiders, the Cessnock Goannas junior said he is keen to start the next stage of his rugby league career with Wests Tigers.
“I’m really excited about the opportunity to join Wests Tigers,” Edwards said.
“It’s a great Club and I’m looking forward to working under JT (Jason Taylor).
“Hopefully I can complement the side nicely and grow with the team.”
