​Raiders quarterback Derek Carr left Sunday's game against the Broncos with an apparent back injury, causing E.J. Manuel to have to enter the game for Oakland.


The Raiders are scheduling an MRI for their franchise quarterback, and all fans are on the edge of their seats.

Carr was injured at the end of last season, and it essentially derailed their season. 


Now, with another injury, if he is out for any extended period of time, it could ruin their season again. Remember, Oakland enter this season as legitimate Super Bowl contenders. 


If Carr's injury proves to be serious? Goodnight. 

Raiders fans will be biting their nails until the MRI results come out, but if he is out, Manuel will need to step in as the new starter. 


Manuel, who has 19 touchdowns and 15 interceptions in his career, would be a major drop off from Carr.
