Hamani Stevens is used to seeing different people on his left. With the litany of injuries the Oregon offensive line has suffered this season, a host of teammates have lined up to his left at tackle.

The one constant has been to his right, where senior Hroniss Grasu has been a mainstay at center.

Until now.

Though offensive line coach Steve Greatwood called center Grasu "day-to-day," Stevens, Oregon's left guard, said his teammate is expected to miss "a couple of games" following a leg injury suffered during Oregon's 51-27 win over Utah on Saturday.

"It was strange to see because I've never seen Hroniss hurt," Stevens said. "We've never seen it before. It looks like he'll miss a couple of games. It's obviously a big loss. We'll have to step us as a team."

Grasu's injury adds to a series of setbacks suffered by Oregon's offensive line. Tyler Johnstone hasn't played a game after tearing his ACL during fall camp. Andre Yruretagoyena has missed eight games after injuring his leg in Week 2 against Michigan State. Jake Fisher missed two games, including Oregon's loss to Arizona. Matt Pierson has missed a game and counting after injuring his MCL against Stanford.

Stevens was briefly injured against Washington, but just missed a series. Other than that, he and right guard Cameron Hunt are the only two on the line who have been relatively unscathed this season. Stevens said it's been a challenge to get on the same page with every new person on the line, but it's something that the team has embraced as the Ducks march into their final two games of the regular season.

With the Ducks on a bye this week, Oregon will likely trot out the formation, from left to right, of Fisher, Stevens, Doug Brenner, Hunt and Tyrell Crosby next week against Colorado. Yruretagoyena could come back either against Colorado or in the regular season finale against Oregon state.

"It's not a burden or anything. The adversity has only made us stronger as a unit," he said. "I'm proud of the way this unit has weathered the storm."
