Swerve! Anthony Johnson vs. Jimi Manuwa -- not Jan Blachowicz -- set for UFC 191

It was signed and sealed, but never got delivered.

While Ultimate Fighting Championship (UFC) officially announced Anthony Johnson vs. Jan Blachowicz for the upcoming UFC 191 pay-per-view (PPV) event, which takes place on Sept. 5, 2015 inside MGM Grand Garden Arena in Las Vegas, Nevada, it recently had a change of heart.

Blachowicz out, Jimi Manuwa in, according to ESPN.

Johnson (19-5) is looking to rebound from his third-round submission loss to Daniel Cormier at UFC 187 earlier this year in "Sin City," while the No. 7-ranked Manuwa (15-1) tries to make it two straight after outpointing the aforementioned Blachowicz last April.

Who ya' got?

UFC 191 features the highly-anticipated rematch between current flyweight champion Demetrious Johnson and the man who took him the distance back at UFC on FOX 6, John Dodson, while Frank Mir is rumored to be throwing hands against fellow ex-champ Andrei Arlovski.
