Seattle Seahawks head coach Pete Carroll told reporters Sunday that running back Kenneth Walker III, who has missed the last three days of training camp, is out with a minor groin strain.
Per Curtis Crabtree of Fox 13 Seattle, the Seahawks are holding Walker out to prevent the injury from becoming an issue.
In addition, Carroll said that rookie running back Zach Charbonnet, who has missed the last two days of practice, is out indefinitely with a shoulder injury.
Last season, Walker missed Seattle's Week 1 matchup against the Denver Broncos after undergoing hernia surgery, but he returned for Week 2 against the San Francisco 49ers.
