The Dallas Cowboys will miss the playoffs for the fifth time in Jason Garrett's seven full seasons as head coach, but owner and general manager Jerry Jones does not sound like he will be making a coaching change.

The Cowboys' 21-12 loss to the Seattle Seahawks knocked them out of playoff contention with their Week 17 finale at Philadelphia left to play.

"Just so we're clear about it, I do understand frustration right after you lose a game that has as much meaningfulness as this ballgame, but I get to look at a lot of different things and have been around a lot of head coaches and coordinators," Jones said. "I feel good about our head coach."

Garrett has a 67-55 record, including his 5-3 mark as the interim coach in 2010, and has led the Cowboys to the playoffs twice in 2014 and '16. The Cowboys had home-field advantage through the playoffs last season with a 13-3 record but lost to the Green Bay Packers in the divisional round.

Garrett signed a five-year deal after directing the Cowboys to a 12-4 record in 2014.

He was not interested in talking about his future on Sunday.

"My job is to [do] the best job for this football team," Garrett said. "It was a tough loss for us today, and we're going to get back to work and try to finish strong."

After last year, coordinators Scott Linehan (offense), Rod Marinelli (defense) and Rich Bisaccia (special teams) signed extensions. A number of assistants have expiring contracts, though.
