Despite controlling most of their Week 10 matchup against the Pittsburgh Steelers, the Indianapolis Colts had to endure a brutal last-second loss. And the pain didn't end there.

According to Gregg Doyel of the Indy Star, quarterback Jacoby Brissett began exhibiting symptoms of a concussion after the game, and was placed in the NFL's concussion protocol. Brissett will not speak to the media following the Colts' loss.
