ANN ARBOR, Mich. -- Michigan coach Jim Harbaugh certainly has his work cut out for him this offseason as he prepares to fill another coaching vacancy.
According to a report from Fox Sports' Bruce Feldman, U-M defensive back coach Greg Jackson is headed to the NFL to coach the Dallas Cowboys in a similar position.
Jackson's exit marks the third coach on Harbaugh's staff to leave, with former defensive coordinator D.J. Durkin (Maryland) and special teams coach John Baxter (USC) leaving the staff earlier this offseason.
Jackson, who was in his first year at U-M, had a history with Harbaugh. Spending four seasons with San Francisco in the NFL before following Harbaugh to the college ranks.
Along side Mike Zordich, both coaches were credited with improved secondary play this season. With Jackson focused primarily on the safeties, he had a hand in Jabrill Peppers' first full season of his playing career in the collegiate ranks.
