Cooper Kupp shakes his hamstring injury and Justin Jefferson assumes the title for the biggest name dealing with a hamstring injury the same week. Jefferson left the game after his quietest outing of the season and didn’t return, which certainly isn’t a good sign – but the full details of the injury are likely to emerge in the coming days, and we’ll have a better idea of how to treat his situation moving forward. At this point, it’s too early to tell whether or not he’ll miss significant time, but at any rate, having arguably the top fantasy wide receiver leave a game and not return is bad news and should be monitored closely this week.
