The San Francisco 49ers are reportedly expected to place running back Jerick McKinnon on injured reserve ahead of the start of the 2019 regular season.
According to NFL Network's Ian Rapoport, it isn't yet clear if McKinnon will return this season or if his knee injury is season-ending.
McKinnon missed the entire 2018 season with a torn ACL, and it was reported by The Athletic's Matt Barrows this week that McKinnon suffered a "flare-up" in his knee Tuesday, marking the third time it had happened since before training camp.
