Entering a game in which they were forced to start third-string quarterback Jimmy Clausen, the Ravens were outmaneuvered at every turn against a superior Seahawks team. With the loss, and the wins from the Steelers and the Jets, the Ravens were officially eliminated from postseason contention.  The team dropped to 4-9 and faced their first losing season since 2007. This was the Ravens' first game of the season which was decided by more than one possession as the team's first 12 games were all decided by eight points or less.
Question: Including this game, how many games had the Ravens played this season?
Answer: 13
