Sources close to the situation confirmed Alves' withdrawal to MMAWeekly.com following an initial report from MMAJunkie.
There's no word on what exactly happened to force Alves off the card, but the UFC is said to be scrambling in an attempt to find a late notice replacement to fight Perry. With only two days remaining until weigh-ins, it's tough to say whether or not the promotion will be able to find a viable candidate.
Alves was looking for his second win in a row after an impressive outing in his last fight where he handed Patrick Cote a unanimous decision loss in April.
As for Perry, he's gone 3-1 thus far in his UFC career with all of his victories coming by way of knockout or TKO including a vicious finish over Jake Ellenberger in his last fight in April that earned him a ‘Performance of the Night' bonus.
