I can top that easily Charles Goldman had over somewhere between 300 and 400 fights in his entire career but since it was waaaaaay back in the day most of his matches went unrecorded throughout boxing history, if you went to boxrec that record is incorrect since about 300 of his fights went unrecorded BUT he easily beats Reggie Strickland

here, do the research
