The Hawai'i football team is bracing for the worst as two key players — quarterback Tyler Graunke and offensive lineman Keith AhSoon — undergo medical tests today.

X-rays will be performed on the right-handed Graunke's injured right thumb and right wrist. He suffered the injury in Saturday's 45-7 road loss to Oregon State.

AhSoon, the Warriors' best left-side lineman, suffered a knee injury in the first quarter of that game. It is feared he might have ligament damage, which would sideline him for an extensive period. He is scheduled to undergo an MRI today.

Both are fifth-year seniors. Neither is a likely candidate for a sixth season, which usually is awarded for non-football illnesses or injuries that result in unique hardships.

In the best scenario, the Warriors hope that Graunke did not suffer a fracture. After Saturday's game, he wore a brace on his right hand. He said he had difficulty making a fist.

The Warriors stayed overnight in Oakland, and returned to Honolulu yesterday. Graunke told coaches his hand felt better. But the coaches remained guardedly optimistic.

"We have to wait for the tests," head coach Greg McMackin said.

The Warriors are making contingency plans if Graunke is found to have suffered a fracture. Inoke Funaki, who started against Weber State and replaced Graunke in the second half against Oregon State, is expected to be elevated to No. 1 quarterback.

Junior college transfers Greg Alexander and Brent Rausch also will receive extensive work this week. The Warriors have a bye this weekend, and open their Western Athletic Conference schedule Sept. 27 against San Jose State at Aloha Stadium.

Quarterback coach Nick Rolovich said Alexander and Rausch are "even" at this point. Rolovich said both benefitted from watching the offense succeed under Graunke, who rallied the Warriors from a 10-point deficit against Weber State.

Jake Santos, a senior, also might receive some work at quarterback.

Rolovich said Shane Austin, one of the scout-team quarterbacks, has been impressive. Rolovich said he expects Austin, a second-year freshman, to be a "contributor" during his career.

McMackin said the bye is "needed."

"We're a tired team," McMackin said.

The Warriors opened with two road games in the first three weeks.

The bye, McMackin said, will allow several players additional time to heal. Running backs Leon Wright-Jackson (sore arches) and Daniel Libre (high-ankle sprain) aggravated injuries against Oregon State.

Laupepa Letuli, the No. 1 left tackle, did not make the trip as he continues to rehabilitate a slight tear in his left shoulder. Letuli's absence led to AhSoon moving from left guard to left tackle. Videos of the game show that AhSoon suffered his injury when he was inadvertently leg-whipped by an OSU linebacker.

Running back Jake Heun (herniated disc) and defensive tackle Rocky Savaiigaea (sprained triceps) are expected to be available for the San Jose State game. They suffered their injuries early in training camp.

The Warriors will have meetings and conditioning sessions today. They practice from 7 to 9 a.m. tomorrow and Wednesday. On Thursday, they practice from 7 to 8 a.m., then will stage the Scout Bowl from 8 to 9 a.m. The Scout Bowl is a full-contact scrimmage involving redshirts, scouts and developing players.

The Warriors will take off Friday, Saturday and Sunday.
