Anthony Dirrell: I was flat last fight. No excuses

Former super middleweight champion Anthony Dirrell is looking to return in spectacular fashion after his upset loss to Badou Jack a few months ago. Dirrell takes on Mexican veteran Marco Antonio Rubio Sunday afternoon beginning at 4pm EST on CBS. Here is what Dirrell had to say about the upcoming fight:

"Training was great. No complaints. It was a fantastic camp and all the hard work is done.

"I know Rubio is a great fighter. He's fought the big names and he's a great veteran. I'm excited to get in the ring with him.

"I was flat last fight. No excuses. Everyone has their days. You can't pick and choose, it just happens. Anybody that knows me knows that I don't fight like that. It's in the past and I'm ready to fight Rubio.
