You have 2 fighters that are actually the same guy. Mark Doku is a cruiserweight from Ghana that now fights out of Tampa. His full name is Mark Doku Tettah. You also have a fighter listed as 1-0 with the name Mark Tettah. This is the same guy.
Before his fight with jerry Cruz, Mark's trainer (jimmy williams) told me that Mark had just fought the week before and knocked a guy out. After searching on boxrec for results, I figured he was Bs'ing me. Fightnews lists an upcoming bout against Pat Nwamu and Mark is listed as "mark tettah," but his record is listed as 7-4-1 - exactly what it would be if the records were combined.
hope this helps.
