The Dallas Cowboys have confirmed the exit of six members of their staff roster, including assistant head coach Rob Davis and offensive line coach Joe Philbin.

The Texas franchise saw their NFL season come to a close in a 19-12 loss to the San Francisco 49ers in the NFC Divisional round last weekend.

That has signalled the start of an offseason shuffle among head coach Mike McCarthy's ranks, with half-a-dozen faces among those who will depart the team.

Alongside Davis and Philbin, running backs coach Skip Peete, defensive assistant George Edwards, analytics coach Kyle Valero and assistant defensive line coach Leon Lett are also leaving.

"We thank these men for their hard work, dedication and contributions to the Cowboys," McCarthy issued in a statement.

"Each of them represented our team and organisation at a high, professional level with class and commitment to making our team better.

"These were difficult decisions to make because of the great respect I have for each of them as a coach and person of character, combined with the experiences we've all gone through together.

"This is the hardest part of the business, and we wish them nothing but the best."

With a 12-5 winning record in the regular season, the Cowboys finished second in the NFC East behind the Philadelphia Eagles.

They defeated the Tampa Bay Buccaneers in a resounding 31-14 Wild Card round victory to start their postseason campaign, but will now continue their wait for a first Super Bowl appearance since the 1995 season.
