An injury has forced Canadian Roger Hollett off the upcoming UFC 152 card, so Vladdy Matyushenko has stepped in to face Matt Hamill in Toronto.
UFC officials announced the change on Monday.
Matt Hamill will return to action after more than a year away from the sport following his retirement in 2011.
Matyushenko will return to action after a loss to Alexander Gustafsson in his last fight from UFC 141 last December.
The veteran fighter will look to get back on track when he faces Hamill in Toronto as part of the UFC 152 undercard.
