UPDATES, Jan. 12: While several changes have been made to the Cowboys' coaching staff for 2018, a familiar face reportedly will be back on Jason Garrett's crew.

Running backs coach Gary Brown, who had drawn interest from Oakland and Houston, is expected to return to the Cowboys, ESPN's Todd Archer reports.

And according to Archer, Miles Austin is not the only candidate the Cowboys are considering for their wide receivers coaching job. Archer tweeted that Dallas will interview former Indianapolis Colts WRs coach Sanjay Lal.

UPDATES, Jan. 11: Former Cowboy Miles Austin has interviewed for the wide receivers coach position, according to the team's website. Austin currently works in the team's scouting department. The Cowboys did not renew the contract of former wide receivers coach Derek Dooley, who accepted the offensive coordinator position at Missouri.

Out goes offensive line coach Frank Pollack, according to ESPN's Todd Archer, marking the sixth change among assistants since the Cowboys' season ended. Pollack had been with the Cowboys since 2013. The Cincinnati Bengals will hire Pollack.

Interviewing for the opening, Archer reports, is Paul Alexander, who spent more than 20 years with the Cincinnati Bengals. Also reportedly in the mix is Tom Cable, who was recently fired by Seattle.

As previously reported, former Cowboys offensive lineman Marc Colombo is in the mix as well.

Elsewhere on the staff, Gary Brown is staying put. For now.

The Cowboys' running backs coach had been linked to the same position on Jon Gruden's Oakland staff this week, the position that NFL Network's Ian Rapoport now reports will be given to former Indianapolis running backs coach Jemal Singleton.

UPDATE, Jan. 10: Another Cowboys assistant may be headed to Oakland.

According to NFL Network's Ian Rapoport, running backs coach Gary Brown is interviewing for the same position on Jon Gruden's Raiders staff.

This news comes on the heels of special teams coordinator Rich Bisaccia's departure for Oakland, a move made official by Gruden during his introductory press conference Tuesday.

Last week, sources said the Cowboys wanted to retain Brown and were working to make that happen. Brown has been in limbo since the season ended, with his contract with Dallas expiring. Brown joined the Cowboys in 2013 and guided Ezekiel Elliott's first two NFL seasons, along with coaching Alfred Morris and Rod Smith as they filled in while Elliott was suspended six games this season.

UPDATE, Jan. 9 via Brandon George: Cowboys special teams coordinator Rich Bisaccia is now the Oakland Raiders' special teams coordinator.

The Cowboys allowed Bisaccia to get out of his contract and pursue the job in Oakland. Last offseason, Bisaccia signed a contract extension with the Cowboys. In recent seasons, the Cowboys have blocked coaches from interviewing with other teams while still under contract.

New Raiders coach Jon Gruden announced Tuesday during his introductory press conference that he had hired Bisaccia. Bisaccia worked under Gruden from 2002 to 2008 when Gruden was the head coach in Tampa Bay and they won a Super Bowl together in their first season.

Bisaccia joined the Cowboys as their special teams coordinator in January 2013, replacing Joe DeCamillis who left for Chicago. The Cowboys also interviewed then-Buffalo special teams coordinator Bruce DeHaven and former Titans special teams coordinator Alan Lowry for the job at the time. Lowry, 67, hasn't coached since 2013 and DeHaven died in December 2016.

The Cowboys could promote from within to replace Bisaccia. Keith O'Quinn has spent the last four seasons as Bisaccia's assistant special teams coach.

UPDATE, Jan. 8: Stephen Jones has acknowledged that Kellen Moore is a candidate to become the team's quarterbacks coach.

The club informed long-time quarterbacks coach Wade Wilson last week that he wouldn't return. Moore views coaching as the next phase of his professional career and has indicated he's willing to retire to pursue coaching. Jones said Moore is one of the options and will be interviewed later in the week.

Former Cowboys receiver Miles Austin is under discussion to fill the vacancy created by Derek Dooley's departure to Missouri, sources said.

The status of offensive line coach Frank Pollack, who remains under contract, is undetermined. Sources said if a change is made there that former Cowboy Marc Colombo, who has been the assistant line coach the past two seasons, would receive strong consideration.

UPDATE, Jan. 7: Derek Dooley, who declined an extension with the Cowboys after last season, will be the offensive coordinator and quarterbacks coach for the Missouri Tigers.

Jason Garrett informed former quarterbacks coach Wade Wilson on Wednesday that his contract would not be renewed. Wilson had held the position since 2007.

Dak Prescott on Kellen Moore last year: “[He’s] a genius behind the scenes who doesn’t get enough credit for what he does helping me out and helping this offense out...He's an offensive coordinator in his own mind. He's simply a genius when it comes to helping Coach Linehan out.” — Jon Machota (@jonmachota) January 7, 2018

Here's a list of which assistant coaches are staying and which are going:

Going

Rich Bisaccia, special teams -- Raiders

Derek Dooley, WRs coach -- Missouri

Wade Wilson, QBs coach -- Contract not renewed

Joe Baker, secondary coach -- TBD

Steve Loney, TEs coach -- Retirement

To be determined

Frank Pollack, OL coach

Original story, Jan. 5: Head coach Jason Garrett and the Cowboys are still working through coaching staff changes.

Special teams coach Rich Bisaccia has been released from the remainder of his contract and is expected to join Jon Gruden in Oakland. But sources said the Cowboys want to retain running backs coach Gary Brown and are working to make that happen.

Matt Eberflus, the team's passing game coordinator and linebackers coach, is another assistant whose contract has expired. There appears to be interest in him around the league, but sources said the Cowboys hope to keep him in the fold as well.

The status of receiver coach Derek Dooley and offensive line coach Frank Pollack was unresolved as of Friday afternoon.

Quarterbacks coach Wade Wilson and secondary coach Joe Baker were told earlier in the week they would not be back. The contracts of both assistants have expired. Garrett said earlier in the week that tight ends coach Steve Loney plans to retire.
