The fight will take place on HBO prior to the actual pay-per-view.
A veteran whose right hook has gotten him out of multiple scrapes, Lee (34-3-1, 24 KO) won six straight after a 2012 loss to Julio Cesar Chavez Jr., culminating in a knockout of previously-unbeaten Matt Korobov for the aforementioned title. He rallied from an early knockdown to take Peter Quillin to a draw his next time out, then lost a snoozer to Billy Joe Saunders two Decembers ago.
Leatherwood (19-3-1, 12 KO), whose name reminds me of a poorly-written materials commission, has faced John Jackson and Hugo Centeno Jr. as a pro. Jackson knocked him out, as did 16-19 Taronze Washington in 2015. Closer inspection reveals that sixteen of his victories have come over opponents with losing records.
The other three? 2-0, 1-0, and debuting.
So, yeah, the outcome isn’t in any significant doubt, but at least we get Lee back.
