Wisconsin has lost another assistant to the NFL as nickelbacks coach Greg Jackson heads to the San Francisco 49ers.
Jackson, who also assisted former defensive coordinator Dave Doeren with the linebackers, spent only one season with Wisconsin after coming there from Tulane. He will serve as assistant secondary coach with the 49ers.
The Badgers already lost running backs coach John Settle to the Carolina Panthers earlier this month.
"Though his stint in Madison was brief, Greg's contributions to the entire football program were great," head coach Bret Bielema said. "We wish him nothing but the best with the 49ers and want to thank him for his time with the team. He is a good coach with a bright future."
Wisconsin's defensive staff will have a new look in 2011. Defensive line coach Charlie Partridge and secondary coach Chris Ash both were promoted to co-coordinators, and the Badgers hired Dave Huxtable from Central Florida to serve as linebackers coach.
Jackson's departure means one more position must be filled.
