The Titans signed McNichols to their practice squad Tuesday, Jim Wyatt of the Titans' official site reports.
The 26-year-old was waived by Tennessee on Saturday but will join the team's practice squad ahead of the playoffs after Jordan Wilkins (undisclosed) was placed on the practice squad injured list Tuesday. McNichols appeared in 14 games during the regular season and rushed 41 times for 156 yards while securing 28 of 38 targets for 240 yards and a touchdown.
