San Diego’s passing attack just too much. Chargers look to be rolling to their 10th straight win.

Chargers center Nick Hardwick fully practiced all week and is listed as questionable to play in Friday’s game at Tennessee, which will be broadcast live on NFL Network.

The Chargers and Titans hit the practice field on Tuesday — normally a day off for teams — in advance of their Christmas Day NFL-Network matchup in Tennessee, and it looks like San Diego could be optimistic about receiving a boost on its offensive line.

The Titans’ struggling pass defense will have some help against the Jaguars with the return of CB Cortland Finnegan and DB Vincent Fuller. Both players are active today, although the Titans will continue to be without CB Nick Harper (broken forearm), who was ruled inactive.

The Tennessee Titans’ jerseys may be light blue, but not because the sky has fallen — yet. At 0-4, I expected there to be some sense of despair after practice today, in this knee-jerk, reactionary NFL in which we reside.
