WHAT'S AT STAKE

Wyoming is looking for anything positive in a season gone sour on the field and now with the one-week suspension of its head coach Dave Christensen for his profanity-laden outburst against Air Force coach Troy Calhoun. The confrontation occurred two weeks ago but Wyoming didn't suspend and fine Christensen until this week, meaning he will not be on the sideline against Boise State. Boise State has won six in a row .

KEY MATCHUP

Wyoming QB Brett Smith vs. Boise State's front seven. Smith is the engine that makes Wyoming's offense go. Smith is averaging 301.8 yards per game total offense but has missed two games and part of another because of concussions. Boise State's defense is ranked in the top 10 for pass defense (158 yards per game), pass efficiency defense (95.6) and points allowed (13.5). It has held opponents scoreless in the first half in each of the last five games.
