Two Ann Arbor-based professional boxers will put undefeated records on the line Saturday at the Holland Civic Center in Holland, Mich.

Welterweight (147 pounds) Patrick Boozer (3-0) and featherweight (125) Rafael Gramajo (1-0) -- who both train out of A-Square Fight Club in Ann Arbor -- will be part of Saturday’s six-fight undercard.

Former USA Boxing national champion Jordan Shimmell will make his long-awaited professional debut on the undercard, as well, in the heavyweight division.

Undefeated light welterweight (140) Juan Garcia, a Holland native, will fight James Ventry in the main event.
