University of Hawaii offensive linemen David Griffin and Leo Koloamatangi are expected to have expanded roles in Saturday’s road football game against Oregon State.

"We’re giving them a chance," coach Norm Chow said.

It has not been determined where they will be used. Both are considered to be offensive tackles, although Koloamatangi has the versatility to play guard.

"They’re both tall guys with good punch," left tackle Sean Shigematsu said. "They have long arms. They’re good players."

Shigematsu suffered a bone bruise when his right ankle was struck by USC defensive tackle George Uko‘s helmet.

Shigematsu participated in drills on Monday, although he wore the yellow jersey for players on limited-contact status. He is expected to play against Oregon State.

Griffin, a transfer from Mesa Community College, did not play in Thursday’s opener against USC.

Koloamatangi, who redshirted as a freshman in 2012, appeared in a few plays.

"I’m trying to make use of this opportunity," Griffin said. "I’m trying to do what I came here to do."

As a former basketball player, Griffin is agile. He said he has worked on improving his upper-body strength since transferring to UH in January.

"I’m trying to get stronger," Griffin said, "and I’m trying to learn as much as I can from (line) coach (Chris) Naeole."

Koloamatangi said he has no preference between guard and tackle.

"Whatever I can do to help this team," he said.

Warriors hope to have Iosefa at Oregon State

Chow said he is "hopeful" running back Joey Iosefa will be available to play this week.

Iosefa practiced on Monday for the first time since suffering a foot fracture in late July. He wore a yellow jersey.

Chow said linebacker Lance Williams and tight end Jordan Pu‘u-Robinson are not expected to play against Oregon State.

Woodard turned back Kessler twice in one series

Defensive end Tavita Woodard finished with three tackles against the Trojans, but he dominated a three-and-out series in the second quarter.

He knocked down two Cody Kessler passes.

Woodard also was effective in crashing down, which helped bracket the pocket and force running plays inside.

Woodard said the Warriors are given freedom to improvise within defensive coordinator Thom Kaumeyer‘s schemes.

"Kaumeyer lets us do what we want as long as we get to where we’re supposed to be," Woodard said. "We have more confidence in what we’re doing this year."
