Oregon finds itself in an enviable spot Jack Lambert Jersey , entering a bye week as the No. 2-ranked team by the College Football Playoff selection committee.That doesn't mean all is well in Eugene, though.Offensive line woes have been one of the few things hampering the Ducks this season, and those i sues will apparently stretch out even longer, as starting guard Hamani Stevens said star center Hroni s Grasu is expected to mi s the next couple games after suffering an injury ."It was strange to see because I've never seen Hroni s hurt," starting guard . "We've never seen it before. It looks like he'll mi s a couple of games. It's obviously a big lo s. We'll have to step up as a team."The notoriously tight-lipped coaching staff refused to discu s injury particulars with reporters but did label Grasu as "day-to-day."The 6-foot-3, 300-pound redshirt senior has started every Najee Harris Jersey game of his career and was considered a leading All-American and Rimington Award (given annually to the nation's top center) candidate based on his play. Along with Auburn's Reese Dismukes, Grasu was considered one of the top center prospects in the mix for the 2015 .Grasu left the Utah Christian Kuntz Jersey game late in the fourth quarter when he had to be helped off the field with a leg injury and was replaced by backup Doug Brenner, who would be in line to start against Colorado after the team's bye week. One would expect the team to be cautious with only the bottom two teams in the conference (Colorado and Oregon State) left on NFL Pittsburgh Steelers Jersey the schedule. Grasu would have nearly a month of rest and rehab before he would be needed to play in the Pac-12 Championship Game in early December.The lo s of Grasu cannot be understated when it comes to the impact on and star quarterback Marcus Mariota. The two have been on the same page throughout their careers and Grasu has limited the pre sure Mariota faced up the middle. Oregon's opponents prior to the conference title game likely won't be much of an i sue for the team, but they could hamper Mariota's numbers a bit without his best offensive lineman up front. If there is any silver lining, it's that the effect of Grasu's injury could be mitigated by the return of offensive tackle Andre Yruretagoyena, who has mi sed eight games since suffering a leg injury against Michigan State on Sept. 6.Still, there appears to be more reshuffling in store for the Ducks' offensive line the next few weeks, and that's a familiar task for the team.You can follow Carlos Davis Jersey Bryan Fischer on Twitter at .
