The Ravens are expected to hire former Chicago Bears tight ends coach Andy Bischoff as an offensive assistant, according to sources with knowledge of the situation.
Bischoff coached the Bears tight ends for the past two seasons and has long-standing ties to new Ravens offensive coordinator Marc Trestman. Bischoff worked under Trestman in Chicago and previously with the Montreal Alouettes in the Canadian Football League.
Bischoff spent 14 years as an assistant head coach and offensive line coach at Cretin-Derham Hall in St. Paul, Minn., before being tabbed by Trestman to join him with the Alouettes.
During his time at Cretin-Derham Hall, the high school went 168-22 with one state title and 13 playoff appearances. Bischoff helped develop 18 Division I offensive linemen, including NFL offensive lineman Ryan Harris.
Among the prominent former Cretin-Derham Hall players: former Ravens Pro Bowl center Matt Birk, former Carolina Panthers quarterback Chris Weinke, former Dallas Cowboys quarterback Steve Walsh, Arizona Cardinals wide receiver Michael Floyd and Minnesota Twins baseball player Joe Mauer.
Hired in 2008 by Trestman, Bischoff coached running backs, tight ends and was special teams coordinator in Montreal. He also was an administrative assistant to the head coach during his time with the Alouettes.
Bischoff coached Bears Pro Bowl tight end Martellus Bennett, who brought Bischoff to the Pro Bowl to thank him for the job he did coaching him.
Bennett caught 90 passes or 916 yards and six touchdowns last season.
Bischoff graduated from the University of South Dakota in 1994 and has a master's degree from Mankato State University.
