Paulo Costa responds to Bogdan Guskov's callout

Paulo Costa has responded to a callout from Bogdan Guskov. The post is very brief and does not include details about what Costa said in his response or whether he accepted or rejected a potential fight. The nature of Costa's reply and his stance on facing Guskov remain unclear from this announcement. This appears to be part of ongoing social media exchanges between middleweights in the UFC roster.
