Titans WR Calvin Ridley (foot) remained sidelined for Thursday's practice. We still don't have any details on this foot injury, but Ridley's availability for this weekend's game vs. the Lions is up in the air. His absence would leave Tennessee without its top two WRs at the start of the season, after WR DeAndre Hopkins was traded to Kansas City earlier this week. The rest of the WR corps: Tyler Boyd, Nick Westbrook-Ikhine, and Jha'Quan Jackson.
