Dallas has also hired Nick Sorenson to serve as special teams coordinator under new head coach Brian Schottenheimer.

Considered the front-runner for the job when Brian Schottenheimer was hired as Dallas Cowboys head coach, Matt Eberflus is now the team's defensive coordinator, the team announced Tuesday. Eberflus served as the head coach of the Chicago Bears for nearly three seasons before he was fired on Nov.

In addition to Eberflus, the Cowboys hired former San Francisco 49ers defensive coordinator Nick Sorensen as special teams coordinator, replacing John Fassel, who joined the Tennessee Titans after his contract expired. Sorensen previously worked with Schottenheimer in Seattle and Jacksonville.
