After one of the most successful Octagon Returns in UFC history, Thiago Alves will be sidelined yet again, this time so the Pitbull can recover from a knee injury, which will not require surgery according to an ATT representative who spoke to MMAJunkie earlier today.

His opponent, Jordan Mein, will now face 11-1 Brandon Thatch, who is 2-0 in his UFC career.

No word on how long Alves will be out.
