BOISE, Idaho — The blue turf at Boise State University's Bronco Stadium is being replaced with different blue turf for free this summer due to a reflective glare that has irritated fans the last two seasons.

Athletic director Gene Bleymaier says light-reflecting fibers in the current artificial field cause problems for people watching the game in person or on television.

Bleymaier says FieldTurf wants to fix the problem and is doing it for free. The school did not estimate the cost of the project.

The school says work will begin June 21 and should be done by July 30.

Boise State begins practice on Aug. 6 with high expectations after going undefeated last season.
