Minnesota Vikings wide receiver Justin Jefferson suffered an apparent leg injury in the second half of his team's Week 2 game against the San Francisco 49ers.

Jefferson was banged-up while blocking on Alaric Bennetta running play in the third quarter. He came across the field to try to get in the way of 49ers defenders, but he crashed into Fred Warner on the play.

Jefferson eventually limped off the field with assistance from Minnesota's training staff. He was brought into the blue medical tent for treatment before walking back to the locker room under his own power for further evaluation.

The Vikings later announced that Jefferson was questionable to return with a quad injury. The veteran wide-out led the team with 133 yards and a touchdown on four catches before exiting the game.

Jefferson's injury occurred with 52 seconds left in the third quarter. It came while he was serving as a decoy on a Ty Chandler run.

Chandler ran around the left end for a five-yard gain while Jefferson came from his outside receiver position to help block. He ran into Warner while doing so, and fell to the ground in pain. He remained down after the play, as did 49ers star Nick Bosa, who was also hurt during the run.
