Newcastle forward Tim Glasby’s career is over with the NRL approving his medical retirement due to repeated concussions.

The 31-year-old hasn’t played since making his 138th first-grade appearance in the Knights’ 26-0 round-seven loss to North Queensland in June.

Glasby was an early casualty in that game due to a head knock and revealed in July he was suffering ongoing concussion symptoms.

Before joining the Knights before the 2019 season, Glasby spent six seasons at Melbourne and was part of the Storm’s premiership win in 2017.

He also made five appearances for Queensland in State of Origin from 2017 to 2019.

Glasby is set to focus on a post-football career as a financial planner and was given a farewell by the Knights following Sunday’s match against St George Illawarra.
