Waufle coached the Raiders defensive line from 1998-2003. He spent the past six seasons in a similar capacity with the New York Giants. The Giants fired Waufle on Jan. 6.
Dwaine Board has been told by the Raiders that he is free to pursue a job elsewhere in the league. He was hired by the Raiders last offseason.
Waufle is credited with playing an integral role in Oakland's Super Bowl appearance in the 2002 season, as well as New York's Super Bowl appearance in the 2007 season.
"New York's Super Bowl victory over New England featured dominating defensive line play," the Raiders said in a press release announcing Waufle's hiring. "Mike is thrilled with the opportunity to rejoin the Raiders. He and Coach Cable spent six years together at the University of California, where they enjoyed working together."
Waufle and Cable could not be reached for comment.
Meanwhile, managing general partner Al Davis still hasn't decided whether to retain current coach Tom Cable for next season. They are expected to meet again in the coming days to discuss further the situation.
Two Baltimore-area newspapers reported that Baltimore Ravens quarterbacks coach Hue Jackson's interview with the Raiders earlier this week included the possibility of Jackson replacing Cable.
The Times reported Wednesday that Jackson's interview with the Raiders, according to two people familiar with the situation, was for the offensive coordinator position that Cable occupied last season.
"I would vociferously deny that any head coaching interviews are taking place while (Davis) is still meeting with Tom Cable," Raiders senior executive John Herrera said Friday morning.
Davis' history is that of an owner who doesn't interview candidates for a head-coaching position as long as he has a coach in place. Herrera said that remains "accurate."
Jackson could not be reached for comment. The Baltimore Sun and Carroll County Times reported that Jackson interviewed with the Raiders on Thursday, as well. However, there is no confirmation that he was at the team's Alameda facility Thursday.
In other news, the contracts of assistant coaches Aaron Pelch, Rich Scangarello and Bert Leone expired and have not been renewed. Pelch assisted special teams coordinator John Fassel. Scangarello was a quality control coach for offense, Leone a quality control coach for defense.
They are free to pursue employment elsewhere. However, it's also conceivable that the Raiders will approach them in the future about re-signing.
