Gonzaga has held 59 consecutive opponents under 50 percent shooting from the field.
This is the sixth meeting of the programs, but the first since 1970.

Utah State plays at Portland State on Monday.
Gonzaga plays Ohio State in the PK80 Invitational in Portland, Oregon, on Thursday. The PK80 features some of the nation's top teams and should give the Zags a better idea of their talent level this year.
