Thomas will be the line judge and Chaka will be the head linesman.
However, Catherine "Cat" Condi has worked some BYU games and done a fine job, Mendenhall said.
"My guess is when you ask me after the game about them, I won't have noticed a difference, one way or the other," Mendenhall said. "With my sideline demeanor, I am not one that is aggressive with the officials, so I don't think [having two female officials] will affect us that much."
Thomas officiated the 2009 Little Caesars Pizza Bowl, while Friday's game will be Chaka's first bowl assignment.
Fight Hunger Bowl supervisor of officials Mike Pereira said all the crew members earned their way to "this prestigious assignment" with their performance during the regular season.
Not a deterrent
Senior inside receiver JD Falslev said he should be able to play with no complications Friday after breaking his hand during a team activity at the Provo Beach Resort in November. Falslev played against Notre Dame and Nevada but had to leave the Nevada game for X-rays after taking a direct hit.
"I got a helmet right on the metal piece [in his hand]," he said. "That didn't tickle. That didn't feel very good. ... It wasn't fun."
The captain believes the accident, which he called "a freak thing. I wasn't doing something stupid," won't deter coaches from conducting physical team activities like rafting down the Provo River, or surfing the wave simulator at PBR in the future.
"I don't think they will go crazy about [not] having team activities or whatever," he said. "It's just that crazy deals happen."
