Khalil Rountree Jr. faces a massive uphill battle when he takes on reigning light heavyweight champion Alex Pereira in the main event of Saturday's UFC 307. To beat the odds, Rountree will have to find a way to succeed against arguably the most dangerous knockout artist in UFC history.

Saturday will mark Rountree’s first shot at gold in the UFC. The American has won five straight fights, including a win via TKO against Anthony Smith on an episode of Fight Night back in December. He has a career record of 13-5, with one no-contest, also having nine victories by knockout.

UFC 307's main card is available to watch through a variety of PPV providers, including cable operators such as Bell, Rogers and Shaw, as well as streaming services such as DAZN, Sportsnet Plus and UFC Fight Pass. Whichever option you opt for, it's a PPV fee of CA$70 across the board.
