The Baltimore Ravens filled out the rest of John Harbaugh’s coaching staff on Wednesday.

Harbaugh announced new coaching staff assignments, including Chris Hewitt as defensive backs coach, Matt Weiss appointed cornerbacks coach and Drew Wilkins named defensive coaching assistant.

Angulo played in the NFL as a tight end with St. Louis (2003), Minnesota (2004-06), Chicago (2006) and Jacksonville (2007-08).

Macdonald, 27, spent last season as a Ravens’ defensive coaching intern. His main duties included a supporting role with the defensive backs/secondary. Prior to joining Baltimore, Macdonald served as a safeties and defensive quality control coach for the Georgia Bulldogs (2011-13).

Bischoff, 44, spent the last two seasons (2013-14) under new Ravens offensive coordinator Marc Trestman as tight ends/staff coordinator with the Chicago Bears. Prior to his time in Chicago, Bischoff also worked under Trestman with the CFL’s Montreal Alouettes (2008-12) as the team’s running backs/tight ends/special teams coordinator.
