Former UFC fighter Elizabeth Phillips a late addition to Saturday's reshuffled Invicta FC 21

Recent UFC competitor Elizabeth Phillips is a late addition to Saturday’s Invicta FC 21 lineup.

On Tuesday officials announced the cancellation of a planned bout between debuting flyweight Brieta Carpenter (0-0), who suffered a concussion during training, and boxing champion Heather Hardy (0-0).

Invicta FC 21 takes place at Scottish Rite Temple in Kansas City, Mo., and the entire card steams live on UFC Fight Pass.

Although Carpenter vs.  Hardy is a late scrap, officials managed to book Phillips (5-4) vs. featherweight Leah Letson (3-1).

Phillips fights for the first time since four-fight UFC stint that resulted in a 1-3 run. While competing as a bantamweight, the 30-year-old suffered split-decision defeats to recent title challenger Valerie Letourneau and Milana Dudieva. She rebounded for a decision victory over Jessamyn Duke. However, a subsequent decision defeat to Raquel Pennington in August resulted in her UFC pink sleep.

Letson, a 24-year-old KOTC vet who turned pro in 2014, suffered a split-decision defeat to Christina Jobe in her pro debut. However, she’s since rebounded with three straight wins and a pair of knockouts. In her most recent bout, she knocked out Sarah Payant in July.
