The UFC is actively looking for two replacement fighters to step in on short notice for next weekend's card in Brooklyn, New York.
Lineker, who is dealing with a rib injury, was scheduled to fight Cory Sandhagen in bantamweight action, while light heavyweight Cutelaba (14-3, 1 NC), whose reasons for withdrawing are unknown at this time, was set to fight Glover Teixeira.
Lineker (31-8) was originally supposed to fight former champion Dominick Cruz this month but was booked against Sandhagen once Cruz pulled out due to an injured shoulder. Now he won't be fighting anyone.
According to sources, the UFC is hoping to fill both slots with new opponents; however, the promotion has yet to find either replacement yet. If it doesn't, Teixeira and/or Sandhagen will be removed from the card.
