According to The Ring, Vitali Klitschko and Cris Arreola have officially signed up to fight each other on September 26 at the Staples Center. Arreola better walk into the ring in better shape than in his last few fights, or this could end up looking like Vitali vs. Danny Williams. Even with Klitschko's limited mobility, it seems like Arreola's come-forward, brawling style should be tailor made for the elder Klitschko.
