Anthony Johnson out, Andrei Arlovski in vs. Mike Kyle at WSOF 5

WSoF 5 headliner Anthony Johnson has pulled out of his Sept. 14 fight against Mike Kyle due to an injury suffered in training. As a result, Andrei Arlovski has agreed to replace "Rumble" against Kyle in Atlantic City, N.J. The fight will now be contested at heavyweight.
Interestingly enough, it was Johnson who last defeated Arlovski via unanimous decision in March at WSOF 2. The loss snapped Arlovski's five-fight unbeaten streak, and he hasn't fought since then.
WSOF 5 will take place at the Revel Resort & Casino. The event, which will air on NBC Sports Network, will also feature the semi-finals of the promotion's first middleweight tournament.
