Hematomas are relatively common in combat sports like Muay Thai due to the impact and striking involved. Fighters can develop hematomas as a result of contusions and blunt-force trauma. However, without specific information about a particular fighter and their health status, I cannot provide details about who may be suffering from a hematoma at any given time. If you’re interested in the health of a specific fighter, it’s best to check the latest news and updates from reputable sports news sources or the fighter’s official channels.
