The Baltimore Ravens face a must-win situation when they host the Cincinnati Bengals on Sunday and it's anybody's guess who will be their quarterback.
Joe Flacco is listed as doubtful after missing practice all week with a hip injury but it's possible he could still play. Baltimore coach John Harbaugh, who has declined to publicly name a starter, could also go with rookie Lamar Jackson or Robert Griffin III, who received substantial work with the first-team offense Thursday as Jackson missed practice with a stomach ailment.
