Reeves recently interviewed with the San Francisco 49ers about the offensive coordinator's job but a 49ers source said Monday that Reeves informed them he likely would be taking a consultant position with the Cowboys.
Reeves could not be reached for comment. A Cowboys spokesman said he had no information about Reeves joining the organization.
Reeves, 65, has a history as a former player and assistant coach under Tom Landry. Cowboys head coach Wade Phillips also has served under Reeves previously as a defensive coordinator in both Denver and Atlanta.
In his postseason press conference after the Cowboys had a disappointing finish amidst controversy, Phillips said he would change his coaching methodology. He mentioned that he wanted to consult with veteran coaches like Reeves and Marty Schottenheimer about his leadership approach for the 2009 season.
However, sources said that Reeves has discussed a more significant role with the Cowboys as a paid consultant.
If Reeves joins the Cowboys in some capacity, he also would be reunited with his son-in-law, Joe DeCamillis, who was hired earlier this month as the team's special teams coach.
