Derrick Henry in concussion protocol

Titans RB Derrick Henry has been placed in concussion protocol, according to ESPN's Adam Schefter. It's the first documented concussion for Henry, and he has an extra day to get cleared with Tennessee playing Miami next Monday night. But he's still more likely than not to miss that game. Henry's absence would leave rookie Tyjae Spears as the Titans' clear lead back -- and a comfortable fantasy starter.
