Pollard missed Wednesday's practice with an ankle injury, Jim Wyatt of the Titans' official site reports.
The Titans listed him with a foot injury at the end of October and for much of November, but Pollard hasn't missed a game this season and didn't show any obvious signs of being hurt during a 10-6 loss to the Jaguars this past Sunday. An absence for the Titans' upcoming game against Cincinnati on Sunday would leave Tyjae Spears as the likely lead back for Tennessee, although Julius Chestnut might get some carries between the tackles and in short-yardage situations.
