Former Green Bay Packers All-Pro linebacker De'Vondre Campbell drew harsh criticism after he declined to enter the Thursday night game between his San Francisco 49ers and the Los Angeles Rams, a 12-6 loss that all but killed the 49ers' playoff aspirations.
49ers coach Kyle Shanahan revealed the issue during his postgame media availability, telling reporters it was the first time in his career he's encountered something like that.
Campbell declined to set foot onto the field in Santa Clara when starter Dre Greenlaw experienced knee tightness in the third quarter.
