In Lynch's case, his non-participation verifies coach Pete Carroll's comment's Monday that Lynch left the field early Sunday in San Diego because his back was bothering him.
Other than Simon, who had minor knee surgery on Sept. 4, the other injuries are not expected to be serious because Carroll said the team came out of the Chargers without any significant injuries. The four other players all played in San Diego.
Running back Christine Michael and rookie linebacker Kevin Pierre-Louis, both of whom missed the first two games with hamstring injuries, returned to practice on a limited basis Wednesday.
"We think he's ready to go," Carroll said of Michael. “He's practicing today full speed on a limited number of plays. The same for Kevin. The first day back we always monitor their reps, but [Thursday], we'll cut 'em loose."
Tight end Cooper Helfet, who was not on the active roster in the first two games because of a knee injury, was a full participant in Wednesday's practice.
