Seahawks center Max Unger will be out for three to four weeks with injuries to his knee and ankle, Seattle head coach Pete Carroll said Monday.
Second-year player Patrick Lewis is listed as Unger's backup at center.
Unger has been a starter for the Seahawks ever since he was drafted in the second round in 2009. He was selected to the Pro Bowl in each of the past two seasons and was a first-team All-Pro in 2012.
