Gervonta “Tank” Davis defeated unbeaten challenger Francisco Fonseca via a controversial eighth-round knockout 39 seconds into the round.
The 22-year-old Davis (19-0, 18 KOs) landed a series of clean blows before an apparent shot to the back of the head sent Fonseca down. Referee Russell Mora gave the 10-count allowing Davis to earn his 18th stoppage win in 19 professional fights. The fight was originally scheduled to be Davis’ second defense of his IBF Junior Lightweight World Championship, but Davis failed to make weight on Friday, coming two pounds over the 130-pound limit that Fonseca (19-1-1, 13 KOs) weighed-in at.
