Kevin O'Connell provides injury update on WR Justin Jefferson

The Minnesota Vikings got some tough injury news at the very beginning of training camp when wide receiver Justin Jefferson was announced by head coach Kevin O'Connell with a mild hamstring strain.

On Friday afternoon during his media availability, O'Connell gave an update on Jefferson after initially announcing that he would be evaluated "next week," which happens to be right now.

"He'll start doing some more things to begin the process, kind of on the grass. I don't have an update on the timeline, other than I know the reports [that come] back to me have been really positive. I think evaluation with something like this is more so the checkpoints before he's eventually just doing more and more and more. And that does start this week. Don't know if that answers your question other than I didn't have a real update other than that long time before week one, but just based on the fact that he was able to get out and do what he did the other day, is he on track to on a process that would get him in the mix for that first week? Yeah, I've been real careful, even in my dialog with him, about what's what."

It's not much of a surprise that O'Connell isn't giving a timeline. The Vikings are notoriously conservative when it comes to injuries, and there is nothing for the Vikings to win right now during training camp. Ideally, it would be great for the Vikings to have Jefferson back for joint practices with the New England Patriots, mainly because it will help J.J. McCarthy develop chemistry against a full team defense.

For now, the Vikings are in a wait-and-see mode.
