The Los Angeles Chargers are still hoping to avoid it, but first-round pick Mike Williams might need back surgery on his herniated disk that would end his rookie season, league sources tell ESPN.
Williams recently received a second epidural on his herniated disk in a last-ditch effort to have him ready at some time during training camp, though the Chargers are preparing as if he will not be ready by that time, per sources.
The team still is hoping that Williams will respond positively to the second epidural, but also knows there's a real chance he will not and his rookie year will be over before it begins.
