Pettis out of Thomson match

Anthony Pettis has dropped out of his fight with Josh Thomson due to a knee injury.

It was less than 24 hours ago when rumor started leaking out

that Anthony Pettis was injured. Asked about it,

target="_blank">UFC president Dana White told FOX Sports on

Saturday night that Pettis had seen a doctor recently but was still

going to fight Josh Thomson “for sure.”

So much for a sure thing.

Pettis has now been ruled out due to the same knee injury,

scratching the UFC lightweight title fight from the Dec. 14 UFC on

FOX card. In its place, Demetrious Johnson vs. Joseph Benavidez II

will serve as the night’s main event.

The news was broken on Sunday’s edition of

target="_blank">FOX Sports Live.

Johnson-Benavidez II was originally set to go down on Nov. 30

from Las Vegas.

This is the second time in 2013 that the dynamic Pettis has been

forced out of a major fight due to an injury. The first came over

the summer, when more knee woes caused him to withdraw from an

anticipated UFC featherweight championship match against Jose

Aldo.

Instead, he went on to fight lightweight champion Benson

Henderson, defeating him via first-round armbar. The December bout

was scheduled to be his first title defense.

UFC officials told FOX Sports it was not immediately clear

whether Josh Thomson or original top contender T.J. Grant will

receive the first crack at Pettis when he returns. Grant has been

recovering from concussion-related symptoms, and his return

timetable has not yet been publicly disclosed.
