Thiago Alves is reportedly out of his UFC Fight Night 79 matchup against former UFC lightweight champion Ben Henderson, which would've headlined the UFC's debut in South Korea later this month, with a rib injury.
After Twitter user @TalkMMA reported the news initially, MMAjunkie.com came out with a report of their own. UFC officials haven't confirmed the injury.
Alves (21-10) returned to the Octagon last year after two years on the sidelines and picked up a decision win over Seth Baczynski. He followed that win up with an upset TKO over Jordan Mein at UFC 183 this past January, but most recently fell to Carlos Condit earlier this spring.
