Fans attending University of Colorado volleyball games this season will witness a fully functioning experiment.

CU is one of two programs in the Pac-12 Conference this fall that will utilize video replay to review close plays. The Buffs tested the system during the team's intrasquad scrimmage two weeks ago and will use it live for the first time Saturday night in the home opener against No. 13 Penn State.

Though only CU and Oregon will use video replay in the conference, the results of all reviews will be official. Coaches are allowed three challenges per match to contest only certain calls, including whether a ball is in or out, whether there was a net touch or not, touches on blocks, and foot faults on serves.

First-year head coach Jesse Mahoney was a proponent of utilizing the system this season, particularly with the Buffs hoping to eventually host NCAA Tournament games at the Coors Events Center.

"In the NCAA Tournament it will be a requirement to be able to host, so we definitely want to get up to speed with it," Mahoney said. "I think it's good. I think it's a good tool to have, but we need some practice on how to use it and when to use it."
