I can't think of any in the era before netural corners. David Izon-Derrick Jefferson was a bad beating. Izon was getting beat so bad, even Larry Merchant was calling for a stoppage. Then Jefferson suddenly hit the wall and ran out of gas and lost. Arturo Gatti-Wilson Rodriguez
Jack Dempsey vs Luis Firpo. Firpo put him out the ring. Dempsey climbed back in and put on a beat down of his own.
