MMA's top competitors throughout all age groups, from 19 to 46  

Few sports have a larger age range of pros than MMA.  

For instance, take a February Saturday. At the PFL Champions vs. Bellator  

Champions event, 46-year-old Yoel Romero defeated Thiago Santos by unanimous decision  

Both Francisco Prado, 21, and Raul Rosas Jr., 19, had fights at UFC Mexico City later that night. Prado lost by decision, and Rosas withdrew due to illness.  

The three major MMA promotions feature competitors aged 19 (Rosas) to 46 (Romero) who have been active in the last year and are currently winning.  

Age debate raises the question: Which boxers are greatest at their ages?
