According to the Associated Press (via ESPN.com), Lewis violated NFL concussion protocol by remaining on the sideline after being diagnosed with a concussion. Here's an excerpt of a letter sent to team doctors and trainers from the NFL's head, neck and spine committee:

On two occasions last weekend, and contrary to the advice of the team medical staffs, players who had been diagnosed with a concussion and therefore declared ineligible for play nonetheless refused to leave the sidelines as required by league concussion protocols. In one case, the player went back onto the field for one play before being removed from the game.

We emphasize that we find no fault in how the team medical staffs conducted themselves last weekend. If a player refuses to follow your advice and leave the sidelines after being diagnosed with a concussion, we recommend that the head athletic trainer seek assistance from the player's position coach (or another member of the coaching staff) or from another team official to remove the player from the sidelines as soon as possible.
