RENTON – Center Max Unger and tight end Zach Miller are questionable for Sunday’s game against the Indianapolis Colts.

Miller hurt his hamstring this week and didn’t practice the past two days. Miller is Seattle’s best all-around tight end and is also considered the team’s best blocking tight end.

If he’s not able to play — and from the way coach Pete Carroll talked Friday, it sounded like Miller wouldn’t — Luke Willson and Kellen Davis will share the duties.

Willson, a fifth-round draft pick, is a player the Seahawks liked because of his speed and ability to stretch defenses. He has five catches for 76 yards. There were questions about his blocking coming into the season, but Carroll said he has held up.

“I’m anxious to see him play and take over this role with a lot of responsibility,” Carroll said.

Davis, known more for his blocking, has two catches for 31 yards in three games and was whistled for three penalties against Houston.

Unger didn’t play last week because of an arm injury and didn’t practice Friday. Carroll said Unger had some work done on his arm this week, but his recovery hasn’t gone as quickly as hoped.

The Seahawks are already without starting offensive tackles Russell Okung and Breno Giacomini for the second straight week.
