OWINGS MILLS, Md. -- The Baltimore Ravens made a switch to the interior of their offensive line Friday by trading for Tony Bergstrom, the team announced.
The team also is releasing former starter Jeremy Zuttah, according to a source.
The Ravens acquired Bergstrom from the Arizona Cardinals for a conditional 2018 seventh-round pick. Bergstrom, 31, provides experienced depth for the offensive line; the Ravens' top two reserves on the interior were Matt Skura and Jermaine Eluemunor, both of whom have never played in an NFL regular-season game.
This is the fourth team in three years for Bergstrom, who also played for the Oakland Raiders and Houston Texans. The 95th overall pick of the 2012 draft, Bergstrom has four career starts.
The Ravens parted ways with Zuttah for the second time in six months. He was traded to the San Francisco 49ers in March, but Baltimore re-signed him on Aug. 18, nine days after the Niners released him. Upon his return, Zuttah never pressed Ryan Jensen for the starting center position.
The offensive line has been an area of concern for Baltimore. It has been hit hard in training camp, losing three key players with the retirement of John Urschel and season-ending injuries to Alex Lewis (shoulder) and Nico Siragusa (knee).
The other notable move by the Ravens on Friday was the release of veteran tight end Larry Donnell, according to a league source.
