Loaded undercard for Stevenson-Fonfara

Although light heavyweight champion Adonis Stevenson is the star of the show on Saturday night, Showtime (9 ET/PT) and Showtime Extreme (7 ET/PT for preliminary bout coverage) will have a full night of action with five televised fights from the Bell Centre in Montreal.

In the main event, of course, Montreal's Stevenson (23-1, 20 KOs) defends the world title against Andrzej Fonfara (25-2, 15 KOs) of Chicago in a long-planned fight that will take place on Showtime instead of HBO because Stevenson's handlers, adviser Al Haymon and promoter Yvon Michel, engineered his exit from HBO and a much-anticipated fall fight with titlist Sergey Kovalev (although they are all being sued over the Kovalev situation).

There are also two 10-rounders on the Showtime portion: Montreal middleweight puncher David Lemieux (31-2, 29 KOs) against former title challenger Fernando Guerrero (26-2, 19 KOs) of Salisbury, Md., and Houston junior middleweight Jermell Charlo (23-0, 11 KOs) against Japan-based New Yorker Charlie Ota (24-1-1, 16 KOs). Naturally, Haymon is involved in all three fights as he also works with Guerrero and Charlo.

There will also be a pair of scheduled 10-rounders on Showtime Extreme as junior middleweight Julian Williams (15-0-1, 9 KOs) of Philadelphia faces Michael Medina (26-4-2, 19 KOs), of Modesto, Calif., and Montreal light heavyweight Eleider "Storm" Alvarez (14-0, 8 KOs), a Colombia native, faces Alexander Johnson (15-1, 6 KOs), of Washington, D.C.

Originally, one of the undercard fights was to feature Russian light heavyweight prospect Artur Beterbiev (4-0, 4 KOs), now based in Montreal, facing the long-faded former super middleweight titlist Jeff Lacy (26-4, 19 KOs). However, Beterbiev broke a finger and the fight was canceled.
