The lineup for UFC 153 took a massive hit today after UFC President Dana White revealed both featherweight champion Jose Aldo and Quinton Jackson had been forced off the card after suffering injuries while training for their respective bouts. Aldo was set to headline the October 13 event against Frankie Edgar, the latter being a substitution himself after top contender Erik Koch went down while preparing for the match-up. Comparably, Jackson was involved in a co-headlining clash with Glover Teixeira.

“Another amazing day at the UFC. We have some work to do,” wrote White on Twitter.

Replacements are currently being sought for both bouts. The situation marks the second straight time Aldo has withdrawn from a title-fight for health-related reasons.

Perhaps easing the organization’s stress, former WEC featherweight title-holder (and current UFC bantamweight) Urijah Faber went online to say he was in the process of bulking up in case the matchmaking team called him as a replacement for Aldo. Faber was last seen going toe-to-toe with interim 135-pound champion Renan Barao in July, ultimately coming up short in a hard-fought decision loss.
