Ahead of next week's event in Houston, the UFC has made a change to the main card.
The promotion announced on Friday that due to injury, Seokhyeon Ko has been removed from his welterweight bout against Jacobe Smith.
Replacing Ko will be Josiah Harrell, who'll now make his UFC debut on short notice.
The "Muscle Hamster" is an impressive 11-0-0 in pro MMA leading into the matchup, winning 10 of those contests by stoppage. He last fought in January, beating Bekmyrza Dosmatov via third-round TKO as part of a Legacy Fighting Alliance (LFA) card.
Saturday's matchup from the Toyota Center will be a battle of undefeated starts as Smith will also enter the octagon boasting an 11-0-0 record. "Cobe" is 2-0 since making his UFC debut last January, both by stoppage.
The 30-year-old won via first-round TKO in his UFC debut and followed it up with a second-round submission win last June.
As for Ko (13-2-0), this is his second cancelled fight with the UFC after his original debut fight was called off last May due to visa issues. Since then, however, the South Korean picked up back-to-back unanimous decision wins, most recently against Phil Rowe in November.
The UFC has not announced any details about Ko's injury.
Headlining the Fight Night card in Houston on Feb. 21 will be a middleweight bout between former champion Sean Strickland (currently ranked No. 3 in the division) and Anthony Hernandez (No. 4).
