The Tennessee Titans are preparing to face the Miami Dolphins in Week 4 without knowing which quarterback they'll encounter. Tua Tagovailoa is on injured reserve after a concussion, and backup Skylar Thompson may also miss the game due to a rib injury.

Dolphins coach Mike McDaniel is closely monitoring the situation. If Thompson can't play, options include Tim Boyle, who has limited experience, or Tyler Huntley, recently signed from the Baltimore Ravens, who possesses more potential but less familiarity with the Dolphins' system.
