Dana White: Anthony Pettis suffered knee injury, will still fight Josh Thomson at UFC on FOX 9

Talk about some scary mixed martial arts (MMA) news.

Ultimate Fighting Championship (UFC) President Dana White revealed to FOX Sports 1 late Saturday night (Nov. 9, 2013) after UFC Fight Night 32 in Goiania, Brazil that the new UFC Lightweight champion, Anthony Pettis, has sustained yet another knee injury.

Before you get your panties all in a bunch, White went on to make it crystal clear that this would not affect Pettis' upcoming fight against former Strikeforce titleholder Josh Thomson at UFC on Fox 9, which is set to go down Dec. 14, 2013, from Sleep Train Arena, in Sacramento, California.

White put it simply:

"He’s going to fight ... for sure."

White did not elaborate on Pettis' injury, but told Mike Chiappetta that Pettis had spent the last couple days in Las Vegas, Nevada, being seen by renowned orthopedist Dr. Steven Sanders, who after thoroughly examining the 26-year old, informed White that "Showtime" would not require surgery to address the issue.

Pettis has had knee problems in the past, forcing him out of a UFC 163 match against Featherweight Champion Jose Aldo. The setback actually opened the door to a rematch against Ben Henderson at UFC 164, where he went on to capture the Lightweight championship.

It is unclear if this is a recurring injury or something new.

Stay tuned for more as the stacked UFC on Fox 9 card approaches, as well as the health of its line up, including Pettis.
