San Diego Chargers guard Kris Dielman's season is over, as the team placed him on injured reserve because of a concussion, says the San Diego Union-Tribune.

Dielman suffered a concussion on Oct. 23 against the New York Jets, then suffered a seizure on the flight home to San Diego.

To fill the spot, the Chargers signed tackle/guard Ike Ndukwe to the roster, a day after they also added tackle Tony Moll to help bolster a beat-up offensive line.
