Jimmie Rivera was already en route to Las Vegas when he received word John Lineker was out of their scheduled bout on Saturday at UFC 219.

Rivera (21-1 MMA, 5-0 UFC), who was supposed to fight Lineker (30-8 MMA, 11-3 UFC) in a bantamweight bout on the pay-per-view main card at T-Mobile Arena in Las Vegas, now heads to “Sin City” without knowing if he’ll compete.

One thing is certain, though: Rivera wants to fight at UFC 219, and a few potential suitors have already offered to step in.

Brian Kelleher (18-8 MMA, 2-1 UFC), who is coming off a third-round TKO win over Damian Stasiak at UFC Fight Night 118 in October, proposed a 140-pound catchweight with Rivera (via Twitter):

Another name reportedly willing to step in on extremely short notice is Marlon Vera (10-4-1 MMA, 4-3 UFC), according to MMA journalist Farah Hannoun (via Twitter):

The most intriguing option, however, may come in the form of former WSOF champ Marlon Moraes (20-5-1 MMA, 2-1 UFC). Although Moraes has already competed twice since Nov. 11, beating John Dodson and Aljamain Sterling, he’s apparently ready to enter the octagon again (via Twitter):

As of Sunday afternoon, Rivera told MMAjunkie via text message that he’s “not sure what’s going on” and is “going to see what happens.” UFC officials are actively searching for a replacement for Lineker (who originally replaced ex-UFC champ Dominick Cruz in the bout), and it remains to be seen if a deal can get done.
