He was originally slated to miss two games following the concussion and a grand mal seizure suffered on the plane ride home.
The team's reaction to Dielman's concussion came under scrutiny by the NFL and the NFL Players Association. He did not come out of the game even though he was visibly staggered by the injury, and wasn't diagnosed until afterward.
The Chargers signed offensive lineman Ikechuku Ndukwe to replace Dielman on the roster. Left tackle Marcus McNeill suffered a stinger and right guard Louis Vasquez injured his left ankle Thursday night in a loss to the Oakland Raiders.
