Hamilton was seen holding his left hip during Thursday's joint practice session with the Packers, Giana Han of TheBaltimoreBanner.com reports.
Hamilton was accompanied by trainers after sustaining a hip injury during a one-on-one drill against Packers wide receiver Christian Watson. Head coach John Harbaugh told reporters after Thursday's practice that Hamilton's injury is not serious, per Han. Hamilton will not likely play in Saturday's preseason game against Green Bay, but he should be good to go for Baltimore's regular-season opener against Kansas City on Sept. 5.
