Minnesota Vikings’ star receiver Justin Jefferson continues to sit out training camp practice with a mild left hamstring strain. Kevin O'Connell has "zero worry" he'll be ready for Week 1.

“But you still want to have him back sooner rather than later,” O’Connell added. “Like I said, zero worry about the opener, but there’s a lot of time in between now and then. What that looks like, we’re gonna be smart, but at the same time, he wants to get back out there. He does not want to stay wearing what I wear to practice for much longer.”
