PROVO — For the fourth straight practice, both wide receiver Cody Hoffman and defensive back Joe Sampson were conspicuously absent.

Both players have been sidelined due to disciplinary issues.

Coach Bronco Mendenhall said there's a chance they could return to practice today, though he added that it depends on whether they meet certain criteria that he's set for them.

"We'll go until we feel great about where they are," Mendenhall said.

Quarterback Riley Nelson said he's not worried about Hoffman being game-ready despite the lost practice time.

"Cody will be perfectly ready. I know he wants to be on the field," Nelson said. "But the reason why he's not is not in his control. There's nothing we can do about it. I'm not worried about him. I know that he's staying in shape and I know that when he is allowed to come back with us, he'll hit the ground running."

Nelson said that both Hoffman and Sampson are participating in team meetings.

"Let's get all that stuff taken care of and get them back on the field," he added.

Asked if the two players' situations were coincidental or related, Mendenhall replied, "A bit of both. I wouldn't be worried, though. When they come back out to practice, whenever that is, we'll all be happy."

SORENSEN UPDATE: Placekicker Justin Sorensen underwent back surgery during the offseason but is still dealing with back pain. He was scheduled to undergo an MRI Tuesday.

Mendenhall said he is still expecting Sorensen to be ready for kicking duties in the season-opener against Washington State on Aug. 30.

In the meantime, punter Riley Stephenson has been working on field goal kicking, while backup quarterback Taysom Hill has attempted a couple of PATs.

SAY CHEESE: BYU players and coaches participated in "Photo Day" at the indoor football facility Tuesday afternoon.

They not only posed for photos, but they also taped video segments for BYUtv, and for segments to be shown on the new big screen at LaVell Edwards Stadium before and during games.

MONEY MAN: Sophomore safety Craig Bills recently returned home from a mission, but he has made a big impact in fall camp. Bills is seeing a lot of time on the field, especially in light of Sampson's absence.

"He looks great," Mendenhall said of Bills. "He'll have a significant role for us this year. I'm really impressed with him."
