McGregor played his last season in the NBL in 2009, finishing with the Gold Coast Blaze after 14 successful seasons, which included Boomers representation.
He moved to the Maitland Mustangs following his retirement from the NBL where he took up the role of Maitland Basketball Association's development officer. After helping the Mustangs reach the Waratah Australian Basketball League grand final, McGregor has since decided to move on to a new career.
"I've got a mate who owns a waterproofing company, so I'm going to be working with him and I'm going to apply to join the fire brigade," McGregor told the Newcastle Herald.
"I've been playing basketball at a high level since 1996, so I'm keen for a bit of a break."
McGregor said he’s keen to resolve an ankle injury before he picks up a ball again, which he aggravated playing against the Sydney Kings in an NBL pre-season trial in Maitland in August this year.
McGregor leaves behind a career that saw him take the NBL rookie of the Year Award for the Newcastle Falcons in 1996. He won an international Goid Medal with the Australian Under 22 Men's Team, alongside the likes of Chris Anstey, Sam MacKinnon and Frank Drmic. He was the first player signed to the new Gold Coast NBL franchise.
Though disappointed about leaving Maitland, he was looking forward to returning to the Gold Coast with his wife and kids.
