The Packers usually wait until the last possible minute to give injury reports. Maybe to try to deceive other teams, or to be 100 % sure about injuries before reporting on them.
No one wants to see any player from any team get injured, but they all know the risk and have all agreed to take that risk.
Team medical staffs are better than decades past, yet players still get injured for not being properly warmed up. I suggest that in addition to what is done to warm up, that heating pads be positioned under the sideline benches. These safe heating pads could quickly be applied a body area by a qualified trainer. Ice is already prepositioned for when it's needed.
