Spears (ankle) wasn't spotted on the field during the media-access portion of Wednesday's practice, Jim Wyatt of the Titans' official site reports.
Head coach Brian Callahan said earlier this week that Spears was "day-to-day" with an ankle issue that's not believed to be serious, but the running back's absence from the early portion of Wednesday's session makes his status worth monitoring. If Spears is limited or out Sunday against the Packers, Tony Pollard would be in line for a larger portion of the backfield snaps and touches.
