"I think it sends a very clear message about the values we support here," said his brother Ryan, 27, who is studying for his masters in physics. "The values definitely include no sexual relations outside of marriage."
He said that Davies' absence was a big blow to the team, which was reflected in the loss to New Mexico.
"It's kind of a fall from grace. It's unfortunate that we didn't do better last night," Ryan Sayer said.
Before the New Mexico game, coach Dave Rose said during his show on KSL radio that Davies' dismissal "was a surprise to everyone."
"What he's feeling right now is that he's let people down, let teammates down, let fans down," said Rose. "We all know what we sign up for when we come to BYU. The way he handled the mistake, he did the right thing."
A year ago, the star running back for BYU's football team, Harvey Unga, had to withdraw from the school along with his girlfriend, a basketball player for the college's women's team, because they were having sex. The couple had been dating for three years and they later married.
