Four Green Bay Packers have been bitten by the injury bug in the first few team practices. Running back Aaron Jones is on the sidelines with a hamstring injury dating back to last week. Linebacker Jake Ryan and defensive back Kentrell Brice had to be helped off the field Monday. Defensive lineman Mike Daniels left Ray Nitschke Field under his own power — but limping. The team hasn’t released a formal assessment of the injuries so far, but the players are expected to be back soon.
