The Philadelphia Eagles are placing starting left guard Landon Dickerson on injured reserve due to a knee injury sustained in the team's season opener, a source told ESPN's Adam Schefter. Dickerson will miss at least the next four games as a result of the IR designation. Dickerson reportedly described his performance in the opener as a 'complete liability' due to the injury, underscoring the severity of the issue. His absence is expected to force changes to Philadelphia's offensive line rotation in the coming weeks.
