Boise State senior offensive guard Joe Kellogg will miss Thursday's game against BYU, the Idaho Statesman reported.

Kellogg, a three-year starter for the No. 24-ranked Broncos, will be replaced by junior Spencer Gerke, who started in place of Kellogg in two games last year when Kellogg was out with a knee injury.

The most experienced Broncos starter, Kellogg has seen action in each season since his freshman year of 2009. He's on both the Outland Trophy and Lombardi Award watch lists. Boise State has finished first and third in sacks allowed the last two seasons, surrendering .63 per game in each season.

Boise State dropped their opener 17-13 to Michigan State and defeated Miami (Ohio) 39-12 in their second game.
