EAGAN, Minn. -- Vikings wide receiver Justin Jefferson sprained the AC joint in his left shoulder, a source told ESPN's Adam Schefter, but the injury is not considered to be serious.
The injury happened at the halfway point of Minnesota's Friday afternoon practice. Jefferson fell onto his left shoulder after he caught a slant from quarterback Kirk Cousins with cornerback Bashaud Breeland in coverage in 11-on-11 drills and immediately grabbed for his shoulder. It was the third straight target for Jefferson, who caught a 22-yard pass on a corner route two plays prior.
