3:35pm: We now have conflicting info regarding Williams. Two sources with direct knowledge of the situation tell Ian Rapoport of NFL.com (on Twitter) that surgery is not a consideration, though it was a possibility as recently as three or four weeks ago. Williams, he hears, is improving.
3:04pm: Awful news for the Chargers. Rookie wide receiver Mike Williams might need season-ending surgery on a herniated disk in his back, league sources tell ESPN.com’s Adam Schefter. 
Williams recently received a second epidural on his back in a last-ditch effort to get him ready in time to participate in training camp, even if it only meant participating in the latter portion of it. As of right now, the team is unsure about whether he’ll be able to take the field in August. They’re hoping he’ll respond well to the epidural, but if he does not, there is a real chance that he will miss the entire 2017 season.
“This may be a lot more serious than people thought,” said one source who spoke with Schefter.
The Chargers have known about the issue since at least May, but it’s not clear when the injury first occured. Williams’ issue first became apparent to the Bolts during the rookie minicamp in the spring, but one source said it’s possible it was injured at the combine and during his pro day. Williams performed well at both events, so the Chargers might not have picked up on the problem.
The Chargers selected Williams with the No. 7 overall pick in this year’s draft. Los Angeles was hoping to slot Williams in as the team’s No. 2 wide receiver this year, providing support to top target Keenan Allen. If Williams is ruled out for the year, it will be a major setback for the Chargers’ offense.
SMH! *Sigh* What else is new…Should have drafted Malik Hooker!
Karma’s a bitch. San Diegans rejoice!
Tyrell Williams is so underrated. That guy balls and will only get better. As a number two with Keenan Allen healthy, and without Mike Williams taking targets, look for him to improve on last year’s breakout. I still don’t have any idea why the Chargers took Mike Williams in the top 10 when they had so many needs on defense and OL. Allen, Tyrell, Benjamin, Inman, Gates, Henry, Gordon. They have plenty of guys to throw to. I don’t think this loss will affect the LAC offense as much as some people think. But they COULD have added another cornerstone piece to that defense. I agree Gooch, Malik Hooker would have been a nice pick.
It’s a poorly run franchise. They deserve this. The player doesn’t…
Ps f you Spanos
Last year was tyrell’s first real chance to contribute. So, it’s hard to say he is underrated. However, if he stays healthy, he should become a stud.
