Head Coach Anthony Lynn began his Monday press conference announcing that Philip Rivers is in the concussion protocol.

"Phil came in today and self-reported concussion symptoms," Lynn said.  "He's seeing our doctors and being evaluated.  He's now in the concussion protocol, and we'll evaluate him for the rest of the week."

The news came as a surprise to the head coach, and the team doesn't know what play it occurred on.

One of the toughest players in the NFL, Rivers hasn't missed a single game since taking over as the starter in 2006.  He famously played days after knee surgery in the 2008 AFC Championship Game against the New England Patriots. With 185 consecutive starts, Rivers has the second longest streak of any current quarterback after Eli Manning (208).

So, what are Rivers' chances of keeping that streak alive and playing Sunday against the Buffalo Bills?

"I hope good," Lynn said.  "Some players go through it in a week and they come out OK.  They practice Wednesday.  We'll see where he's at.  Like I said, this was news to me."

Still, the health of the quarterback will always be prioritized.

"He needs to pass the test first," Lynn continued.  "If he's not healthy, we do not want him on the field.  But if he's healthy and ready to go, yeah, (he'll be out there)….He would definitely be up (when cleared).  At this stage of his career, he can play without practice.  He would definitely be up."
