UFC Vegas 89: Amanda Ribas vs. Rose Namajunas fight card, start time, channel guide, betting odds

The UFC hosts the second of two back-to-back UFC APEX cards on Saturday, March 23. Headlining the card is a women's flyweight fight between No. 8 ranked Amanda Ribas (13-4-0) and former UFC strawweight champion Rose Namajunas (12-6-0).

Namajunas has lost two in a row, including losing her strawweight title and her flyweight debut. She will need a win in order to boost her back up in the contender talks if she hopes to ever become a UFC double champion.

Ribas is coming off a win over Luana Pinheiro in November, but that was a strawweight bout. She'll be fighting Namajunas at flyweight for this contest.

In the co-main event is a heavyweight scrap between Karl Williams (9-1-0) and Justin Tafa (7-3-0). Tafa was supposed to fight Marcos Rogerio de Lima at UFC 298 but a last minute injury deemed him unable to compete. His brother Junior stepped into his place but lost the bout.

There are also several fighters making their UFC debut on the card, so look for plenty of fighters with something to prove.

Here's the full fight card, subject to change.
