Kevin Johnsons famous resistance broke to force a stoppage of their American veteran in Newcastle.
The heavyweight was made to deal with a late change of opponent, together with Johnson replacing the injured Gabriel Enguema, but Bakole generated strain to become only the third man to halt his 40-year-old competition.
Johnson had shot Daniel Dubois the space in a points reduction last year and was content to remain tucked up with a defensive casing since Bakole probed for openings.
However, the former world title challenger showed signs of distress at the next round, turning away following a sustained attack from Bakole, who began to land his own hand.
Johnson shield could unravel in the fifth his head jolted back to induce the referees intervention.
On the identical bill, Lawrence Osueke has been forced to settle for a draw with Ricky Summers after a experience.
Osueke received a 100-92 verdict although Summers gained a score in their own favor, and the third made it a lure that was 95-95.
Earlier Konrad Stempkowski on the road floored to a points success that was broad.
