This bout, believe it or not, started as Thiago Alves vs. Yoshihiro Akiyama.
Unfortunately the injury bug has mutated into a swarm and continues to gobble up any careless fighter in its path. After a "sexy" injury to Akiyama, Ultimate Fighting Championship (UFC) tapped Siyar Bahadurzada to take his place.
Then "The Pitbull" had to be put down after getting hurt in practice.
Now Chris Clements steps up on short notice to try and cement his place among the baddest of the 170-pound bad, taking on "The Killer" at the UFC 149: "Aldo vs. Koch" pay-per-view (PPV) event from the Scotiabank Saddledome in Calgary, Alberta, Canada, on July 21, 2012.
UFC.com announced the line-up change earlier today.
Clements (11-4) made his Octagon debut with a split decision win over Keith Wisniewski at the UFC 145 event earlier this year in Atlanta. His win over "The Polish Connection" pushed his current win streak to five. Meanwhile, Bahadurzada (21-4-1) also made a successful UFC debut by recently pasting Paulo Thiago at UFC on FUEL TV 2 in Sweden.
Who gets it done up north?
UFC 149 features a main event title fight between reigning featherweight champion Jose Aldo putting his 145-pound title on the line against the dangerous striking attack of division number one contender Erik Koch.
Other main card match-ups include Antonio Rodrigo Nogueira's return from injury to face off against Cheick Kongo while Michael Bisping tries to get back into the 185-pound title hunt against middleweight "Barbarian" Tim Boetsch.
