The Broncos, off to their best start in 41 years, will face their toughest test yet as they travel to Seattle to take on the Huskies at 3 p.m. Sunday.
Brooke Pahukoa is leading the Broncos (8-0) at 15.5 points per game, and Shalen Shaw is adding 11.9 points and 7.1 rebounds per game.
Washington (9-1) is on a six-game winning streak and is led by seniors Kelsey Plum and Chantel Osahor.
Plum is averaging an NCAA-best 29.7 points per game and needs 23 points to become the Pac-12 all-time leading scorer. Osahor averages 15.1 points per game and an NCAA-best 15.4 rebounds.
A win would give BSU coach Gordy Presnell 600 career victories.
