Seattle Seahawks cornerback Walter Thurmond will miss the remainder of the season with a cracked left fibula, head coach Pete Carroll announced after Seattle's 6-3 loss to the Cleveland Browns via Seattle sports radio station 950-KJR's Twitter feed.
A fourth-round pick out of Oregon in 2010, Thurmond had assumed the starting left cornerback job on a permanent basis after Seattle placed Marcus Trufant on injured reserve with a back injury.
In six games, including three starts, in 2011, Thurmond had 12 tackles and two passes defensed.
Thurmond was injured while defending a deep pass to Browns wide receiver Greg Little just after the two-minute warning in the first half. 2011 fifth-round pick Richard Sherman replaced Thurmond in base defense with Kennard Cox replacing Thurmond as the slot corner in nickel defense.
The Seahawks are expected to get nickel cornerback Roy Lewis back from the PUP list within the next two weeks.
