Zab Judah vs. Carlos Baldomir was a professional boxing match contested on January 7, 2006, for the WBC and The Ring welterweight championship.

[1] After stopping Cory Spinks in February 2005 to win the Undisputed welterweight championship Zab Judah had made one successful defence, scoring a 3rd round TKO over Cosme Rivera in May, before agreeing to big money bout with WBC Light Welterweight Champion Floyd Mayweather Jr., which was tentatively scheduled for April 2006.

"[7] Bell's reign as undisputed would last just over two months as he was stripped of the IBF belt on 31 March after undergoing dental surgery and subsequently withdrawing from a fight with mandatory challenger Steve Cunningham scheduled for 6 May.

During the prefight introductions, instead of touching gloves to show sportsmanship, Judah unsportingly punched Baldomir on the thigh, earning a rebuke from referee Arthur Mercante Jr..

The welterweight division would remain split for 17 and half years until Terence Crawford defeated Errol Spence Jr. in July 2023.
