Jason Garrett and the Dallas Cowboys are on the verge of agreement on a new five-year contract.

A team source told ESPN's Ed Werder of the deal: "It's not done, but close."

Garrett took over as the Cowboys' interim coach in the middle of the 2010 season. He went 5-3 after a 1-7 start to the year brought an end to the Wade Phillips era.

The Cowboys finished 8-8 in each of Garrett's first three years as the full-time coach before breaking through to the playoffs this season.
