Bullock (calf) is listed as questionable for Sunday's game against the Bengals after missing practice Friday, Jim Wyatt of the Titans' official site reports.
With Bullock, who was inactive in Week 11, looking iffy for Week 12 at this stage, Caleb Shudak (leg) could be activated from the PUP list before Saturday's deadline for roster moves to handle the Titans' kicking duties.
