The Storm prop has made 94 NRL appearances all with Melbourne, becoming a key part of their front row.
The 29-year old had a breakout campaign in 2017, helping Queensland win the Origin series and playing a role off the bench in Melbourne’s premiership triumph.
Newcastle coach Nathan Brown is excited for what Glasby will bring to the table in 2019.
“He is with the leadership group in Melbourne now and will also provide valuable leadership here at the Knights,” Brown told www.newcastleknights.com.au.
“His form is consistent in the small parts of the game and he’s very efficient in both his defensive and attacking areas.
“Probably the best compliment we can give him is that teammate Cameron Smith pushes him to not only be in the Melbourne team, but also pushes him to be in the Queensland team and you probably can’t get any bigger endorsement than that from the Australian captain and one of our games greatest ever players.
“Tim being an Origin player and grand final winner is important for our squad, with his quality and experience set to add a lot to our forward pack.”
