At one point during the 2014 season, it seemed there was a good chance a 49ers coach could end up bolting for Oakland. Now the traffic appears to be going in the opposite direction.

The 49ers on Friday interviewed Jason Tarver, who served as the Raiders’ defensive coordinator the past three years, a league source said. The interview presumably was for the same position on Jim Tomsula’s staff. Tarver, 40, spent 10 seasons with the 49ers, including coaching the outside linebackers from 2005 to 2010.

That means he’s familiar with Tomsula – they worked four years together – as well as many members of the 49ers’ defense, including linebackers Patrick Willis and NaVorro Bowman and lineman Justin Smith. The latter is contemplating retirement but might be more inclined to play for Tomsula.

Tarver was the defensive coordinator at Stanford in 2011 before joining the Raiders the following season. Oakland finished 21st in total defense this past season and 22nd and 18th in the two seasons prior. The Raiders’ defense held the 49ers to 248 yards and had two interceptions in a 24-13 win against San Francisco in Week 13.

Tarver is the only known candidate to have interviewed for the position.

As for offensive coordinator, Tomsula on Thursday said he didn’t want to get into specifics because of the fast-changing nature of coaching searches. He said he also wanted to avoid tampering.

It would only be tampering if a prospective coach were still in the playoffs. One potential offensive coordinator who fits that description is Colts assistant Rob Chudzinski, who once ran the Browns’ and Panthers’ offenses. He was reportedly targeted as an offensive coordinator by then-49ers coach Mike Singletary in January 2009 but was one of several men – Scott Linehan was another – who turned down the job.

Meanwhile, former 49ers defensive coordinator Vic Fangio will interview for the same job with Washington today, a league source said. The 49ers initially denied Washington’s request to talk to Fangio. Fangio also could draw interest from the Chicago Bears and their new head coach, John Fox.

Washington also has spoken with former 49ers assistants Ed Donatell and Eric Mangini about its opening.
