Bader (21-5) replaces Nogueira's original opponent, Alexander Gustafsson, who withdrew from the event for undisclosed reasons. MMAFighting.com first reported the switch.
Fighting out of Power MMA in Arizona, Bader scored a highlight knockout over Ilir Latifi earlier this month in Hamburg, Germany. The 33-year-old is 6-1 in his last seven fights, although the loss was a resounding first-round knockout to Anthony Johnson in January.
Prior to that loss, Bader had put together a five-fight win streak. All five victories came via decision.
Nogueira (22-7) hasn't fought since a first-round TKO over Patrick Cummins in May. The Brazilian snapped a two-fight skid in the win.
