Jason Garrett will not return as Cowboys head coach

FRISCO — Jason Garrett is out as coach of the Dallas Cowboys after missing the playoffs with an underachieving team in a make-or-break season.

The Cowboys made it official Sunday.

Garrett had the second-longest tenure with the franchise at 9½ seasons behind Tom Landry’s 29 years. Garrett took over when Wade Phillips was fired halfway through the 2010 season.

The Cowboys finished 8-8 in the final year of Garrett’s contract. It’s the fourth time Dallas finished 8-8 and missed the postseason under the 53-year-old coach. The Cowboys fueled high preseason expectations with a 3-0 start before dropping eight of 12 and losing control of their playoff fate.
