Minnesota Vikings wide receiver Justin Jefferson suffered a mild hamstring strain and will be held out of practice, head coach Kevin O'Connell announced Friday.
Jefferson will be re-evaluated next week.
"The best thing is we avoided anything serious," O'Connell said, according to ESPN's Kevin Seifert. "I see no concerns in regards to (Week 1) and have no worry at all that we'll be able to get Justin ready to go for the regular season."
