We'll learn more about new Vikings coach Mike Zimmer when the team introduces him Friday morning. Until then, it's safe to assume the guy works quickly.

Amid an ESPN report that veteran former NFL head coach and noted offensive mind Norv Turner is close to becoming the Vikings' offensive coordinator, another report has surfaced that Zimmer has landed his defensive coordinator as well.

According to Fox Sports' Alex Marvez, Dolphins linebackers coach George Edwards will leave Miami to join Zimmer as defensive coordinator.

Keep in mind, however, that the team has not announced any hires to Zimmer's coaching staff.

Edwards, 47, coached together in Dallas with Zimmer. From 1998 to 1999, they were position coaches together. From 2000 to 2001, Zimmer was defensive coordinator while Edwards continued to coach the linebackers.

This would be Edwards' third stint as an NFL defensive coordinator. He was the defensive coordinator for the Redskins in 2003 and the Bills from 2010 to 2011. Edwards was in his second season as the Dolphins' linebackers coach.

Turner, meanwhile, has been a head coach in Washington, Oakland and San Diego. His greatest success, however, came as the offensive coordinator on the Cowboys teams that won two Super Bowls during the 1990s.
