SALT LAKE CITY -- Hours after coach Kyle Whittingham said No. 24 Utah didn't sustain any season-ending injuries in its loss to California, the Utes found out that three-year starting center J.J. Dielman will miss the rest of the season because of a lower leg injury.

Whittingham said several players were having MRIs on Monday to determine the severity of their injuries. Dielman clearly got bad news, as the school said he was out in a release Monday afternoon. Dielman joins former starting defensive end Kylie Fitts and tight end Siale Fakailoatonga on the sideline for the rest of the season.

Utah is coming off its first loss, but it might have bigger problems in its quest for a Pac-12 title. The Utes have been ravaged by injuries at receiver, offensive line, running back, defensive line and in the secondary.

"I'd be here for a half-hour if we start talking about all the injuries," Whittingham said.

Former walk-on Lo Falemaka is next in line on the depth chart, but Utah did not make the junior available to media Monday. He had a slow start, with a pair of bad plays when he entered the game last week, but quarterback Troy Williams said they laughed it off.

"He told me, 'Hey, man, I just had to get my jitters out real quick,'" Williams said. "I told him I understand fully. We have a great team, great guys all around. Next guy just has to step up and take advantage of his opportunity."

Utah lost its No. 1 receiver, Tim Patrick, starting cornerback Reggie Porter and Dielman during Saturday's game. Patrick said he expects to play this week.

Whittingham and Utah give little details about injuries, so Porter's status is unknown. Whittingham did mention that receiver Kyle Fulks had to leave the game last week, and both running back Troy McCormick and receiver Tyrone Smith are banged up.

First-team All-Pac-12 defensive lineman Lowell Lotulelei missed the game against Cal after suffering a shoulder injury against USC. Starting slot receiver Cory Butler-Byrd didn't travel to California, and Whittingham said it was a physical issue. The coach hopes he can play against Arizona.

"There's about a dozen guys who's in that category," Whittingham said.

Sophomore receiver Raelon Singleton had his best game, with career highs in receptions (seven) and yards (98) as the No. 1 option in the pass game after Patrick went down. Williams said he is confident in all his receivers, but Patrick is No. 32 in the country with 429 receiving yards and tied for No. 12 with five touchdown catches. The Utes didn't have a receiver who caught five touchdowns in all of 2015.

Utah already lost senior running back Joe Williams to retirement due to lingering injuries. Whittingham announced that sophomore Armand Shyne has been promoted to starting running back over Zach Moss after he rushed for 99 yards and two touchdowns against Cal.

The Utes (4-1, 1-1 Pac-12) aren't panicking, despite the plethora of injuries. The goal of winning the conference title is still attainable, as No. 21 Colorado (4-1, 2-1) is the lone Pac-12 South team without a conference loss. The Buffaloes host Utah in the regular-season finale. Whittingham doesn't believe anyone in the conference will go undefeated and said a two-loss team will likely win the title.

"It's easy to let yourself fall into that, like, 'Why us?' " Utah safety Chase Hansen said. "But then you realize everyone's banged up. You look at Arizona, and they have the same thing going on with them.

"Honestly, it feels like it happens every year. So there's no point in being surprised. You just have got to be ready. Next guy up. ... No excuses, that's a team motto."
