Some much-needed reenforcement is coming for the Seattle Seahawks defensive backfield. In the wake of injury after injury to the “Legion of Boom,” Seahawks cornerback DeShawn Shead is on his way to playing for the first time this season after spending its first three months on injured reserve. Shead, who has played his entire six-year NFL career in Seattle, practiced for the first time on Wednesday. Though head coach Pete Carroll is keeping expectations low on his veteran defender, Seattle’s coach is clearly excited to have him back on the field – for practice or games.
