UFC Fighter Apologizes For Failed Drug Test, UFC 177 "Countdown" Video, Former Champ Talks Loss

- Gain a new insight into this Saturday's main event at UFC 177 between bantamweight champion T.J. Dillashaw and Renan Barao. The video, part of the "Countdown to UFC 177" special that aired on FOX Sports 1, can be viewed in the video above.

Dillashaw will make his first title defense against the man he won the belt from earlier this year in Barao. The pay-per-view airs from the Sleep Train Arena in Sacramento, California and features a co-main event between Danny Castillo and Tony Ferguson.

- After a stunning knockout loss to Rafael dos Anjos, former UFC lightweight champion Benson Henderson is already planning his return. Dos Anjos scored the win this past weekend at UFC Fight Night 49, landing a clean left that dropped "Smooth."

"I'm still a pretty confident guy," Henderson told MMAjunkie.com. "I just lost, but my confidence isn't shaken. I'm still pretty healthy. We can run it back another 10 times – that's the kind of guy I am. So confidence-wise, that isn't shaken."

Henderson, who protested the stoppage immediately after, admitted it was the right call by referee John McCarthy. The knockout loss was the first of his career.

"It was a flash knockout. They happen," Henderson said. "I wanted to latch on to a single-leg and push him up against the cage. Hopefully take a couple of shots and let the cobwebs clear a bit. As soon as I started to come around to go into the single-leg, 'Big' John (McCarthy) did his job."

- UFC on FOX 12 winner Brian Ortega failed a drug test and faces a suspension and fine from the California Athletic Commission. Ortega, who defeated Mike De La Torre, issued an apology via Instagram for the failed test.

His win will also be overturned to a no-contest, leaving him 8-0 in his career. He had scored a rear-naked choked over De La Torre.
