Anthony Pettis is finding it more and more difficult to sit on the sidelines.

Since defeating Joe Lauzon earlier this year, Pettis has been forced under the knife. While he continues to rehab from shoulder surgery, “Showtime” has had to fend off verbal attacks from Donald Cerrone.

During a recent interview on The MMA Hour, the former WEC lightweight champion let it be known that he is more than willing to face Cerrone, if “Cowboy” gets past Melvin Guillard this week at UFC 150.

If he gets passed his fight with Melvin, and it makes sense for me to fight him, then I’ll do it. If he’s in my way, I’ll take him out. I’m never afraid to fight anybody. I want to be the best lightweight in the world.

Pettis is 15-2 overall, while Cerrone sports an 18-4-1 record. He added that he’s never had any issues with Cerrone before, but “you put him behind a telephone and his little keyboard and a tough guy comes out.”
