Walker (groin) returned to practice Saturday, Brady Henderson of ESPN.com reports.
Sidelined since the first day of Seahawks training camp due to a minor groin strain, Walker didn't suit up for the team's first preseason contest Thursday, which allowed rookie second-rounder Zach Charbonnet to get some run. Walker was contained to individual work Saturday, so he may need to progress to team drills in order to gain clearance to play in one of the final two exhibitions, the first of which comes Saturday, Aug. 19 against the Cowboys.
