Dunlap's release was expected after the Chargers signed Russell Okung to a four-year, $53 million deal on the first day of free agency last week. Okung is slated to start at left tackle, allowing the Chargers to move on from Dunlap.
Dunlap, 31, served as the left tackle for the Chargers for the past four seasons. A solid pass protector when healthy, Dunlap had trouble staying on the field, missing 13 games the past two seasons due to concussion and leg issues.
He was due $5.75 million in non-guaranteed base salary in 2017, and he restructured his contract so he could remain with the Chargers last season. The Chargers will save nearly $5 million in cap space by releasing Dunlap.
He also was arrested in February for allegedly violating a protection order in Nashville, Tennessee.
