Mark Blicavs will celebrate a major milestone when he plays his 100th AFL game on Thursday night.

The Cats big man has enjoyed a remarkable career, having come to the club after initially trying to make the Australian Olympic team as a steeplechaser.

"It's gone super-quickly, looking back on it," Blicavs told Cats Media in the lead-up to the game.

"I've had a few ups and downs, but it's been unbelievable."

Amazingly, Blicavs has missed just four games on his way to 100.

"I've had a really fortunate run with no injuries," he said.

"Hopefully I can play another hundred as fast as I've played this hundred."
