Hawaii receiver Justin Clapp will undergo knee surgery today and miss at least three football games.

Clapp, a fourth-year junior, suffered the torn meniscus in his left knee during a practice last week. Clapp is hopeful of returning for the Nov. 3 road game against Fresno State.

Clapp can play all three receiver positions.

Freshman offensive lineman Kiha Sai will undergo surgery today to repair a torn left labrum. Sai was expected to redshirt this season.

In Saturday’s 47-0 loss to Brigham Young, the Warriors incurred several injuries. The most serious appeared to be to defensive tackles Geordon Hanohano and Siasau Matagiese. Both were diagnosed with neck stingers.

Hanohano has been told he will miss at least a few games. Hanohano will decide on the rehabilitation program after receiving a second opinion. A stinger does not require surgery. This is Hanohano’s second stinger.

Matagiese is expected to play in Saturday’s road game against San Diego State. Matagiese participated in non-contact drills during the Warriors’ one-hour practice on Monday.

Defensive lineman Marcus Malepeai said he has a sprained MCL in his right knee. No surgery is required, but Malepeai is expected to miss the Warriors’ next two games. Malepeai is a defensive end who is capable of playing tackle.

Coach Norm Chow said running back Joey Iosefa and wide receiver Darius Bright might need more recovery time. Iosefa has missed the past two games because of a foot injury. He appeared to be healed before aggravating the injury during a practice last week.

Bright is recovering from a sprained right shoulder.

The prognosis was better for offensive linemen Dave Lefotu, Blake Muir, Sean Shigematsu and Kapua Sai.

Lefotu’s sore elbow will not prevent him from playing against San Diego State.

Muir, Shigematsu and Sai are all having labrum problems. Each underwent an MRI on Monday.

Chow said they are suffering from what is termed a "slap tear," an ailment common for offensive linemen because of the demands of blocking. All are expected to play.

"You have to play through some pain," Chow said. "Most offensive linemen go through that because of all of the extensions they do. … We’ll pad it up. You can’t hurt it any worse (by playing)."

Shutter next in line

Chow said Cayman Shutter is the No. 2 quarterback.

Shutter completed a three-game suspension last week for his no-contest plea to a driving-under-the-influence charge. He played a series against BYU.

"He brings some experience, some maturity," Chow said. "He hadn’t played for a while, but he studied up on it all. He’s very studious."

Shutter’s promotion means David Graves, who started two games at quarterback in 2011, moves back to receiver.

"We need David outside," Chow said. "We’re hurting out there as well."

Warriors leave on Friday

The Warriors will go with a quick-hit approach for this week’s road trip. They will have a walk-through practice at the Ching athletic complex on Friday morning, then depart that afternoon to San Diego.

For this season’s first two road games, they traveled two days in advance.
