San Diego Chargers center Nick Hardwick has been diagnosed with a concussion reports the San Diego Union Tribune.
Hardwick appeared in last Sunday’s Wild Card game for only a handful of snaps before going to the sidelines and later the locker room.
The Chargers turned to Rich Orhnberger who did not have any troubles snapping the ball to Philip Rivers.
On Wednesday the Chargers practiced without  right tackle D.J. Fluker, running back Ryan Mathews and wide receiver Eddie Royal in addition to Hardwick.
