Anthony Pettis says move to featherweight ?not permanent,? expects ?fireworks? against Jose Aldo -

"A lot of things led to my cutting down to 145," said Pettis in a recent interview with New York Post. "I was tired of waiting for a 155-pound title shot."

After getting passed over for former Strikeforce Lightweight Champion Gilbert Melendez, Pettis was matched up against former World Extreme Cagefighting (WEC) comrade Donald Cerrone. Anthony was able to walk right through "Cowboy," stopping him in the very first round thanks to a vicious kick to the body at UFC on FOX 6.

Soon thereafter, Pettis took a chance and asked for a title shot against Aldo via text message due to the fact that "El Nino" had already received the nod at the lightweight title against current champion Ben Henderson.

To the surprise of many, "Showtime" got his wish and was booked to swing leather against "Scarface" at UFC 163, which goes down in Rio de Janeiro, Brazil on Aug. 3, 2013. But, the 155-pound weight class will still have to deal with Pettis down the road because the move down to featherweight is not forever.

"It's not a permanent weight cut (to featherweight)," said Pettis. "But a striker like myself and Aldo, it doesn't really matter what weight class it happens at. It's going to be fireworks either way."
