There are reports that Arman Tsarukyan may replace Justin Gaethje on a UFC card, but it is unclear if this is an actual development or an April Fool's prank. The situation appears to be uncertain, with some outlets suggesting that Tsarukyan's claim may not be true. The status of the UFC White House card and the involvement of fighters such as Ilia Topuria and Arman Tsarukyan remains unclear.
