Jiri Prochazka and Khamzat Chimaev's Sparring Stories Spark UFC Challenge and Warning

Jiri Prochazka responded to Khamzat Chimaev's claims of winning sparring sessions by challenging him to a fight in a cage, warning him that he will show his true power. Chimaev responded by challenging Prochazka to a fight in Sweden in June or July and tagging the UFC and Dana White. Prochazka vacated the light heavyweight title in December due to a shoulder injury, while Chimaev is open to fights at welterweight, middleweight, or even light heavyweight.
