Next month's UFC Fight Night card has taken a hit.

The fight between Angela Hill and Alexa Grasso has been canceled because Grasso was forced to withdraw due to undisclosed reasons, sources told ESPN.

The UFC is currently seeking a replacement to fight Hill (8-4), who is coming off a unanimous decision win over Maryna Moroz in February.

The event, which will be headlined by Justin Gaethje vs. James Vick, will take place Aug. 25 in Lincoln, Nebraska.
