Hart (concussion) practiced fully Wednesday, John Boyle of the Seahawks' official site reports.
Hart exited Sunday's season opener at Indianapolis due to a concussion, and while he was able to handle every drill at Wednesday's session, it's unclear if he's cleared all five phases of the NFL's protocol for head injuries. Until the Seahawks clarify his health, he may not progress enough to make himself available for a Week 2 matchup with the Titans.
