Pat’s update: Not good
The fear is that 49ers' RB Jerick McKinnon tore his ACL, per source. He is scheduled to have an MRI to see the extent of the injury.— Adam Schefter (@AdamSchefter) September 1, 2018
The San Francisco 49ers are putting the finishing touches on the 53-man roster for the Saturday deadline and might have some more decisions to make with the running back position. NFL network reporter Ian Rapoport and local media are all reporting that running back Jerick McKinnon suffered a, “concerning” injury.
Kyle Shanahan said McKinnon will undergo an MRI and the team is “extremely concerned.” He’s part of the 53-man roster for now, but Shanahan said if they get a bad MRI, he would go on IR. The injury happened on the last play of practice, and he landed awkward made a cut.
McKinnon suffered a calf injury in early August, and was pulled from preseason games as a precaution. By all accounts, he was to be ready by Week 1 against the Minnesota Vikings, but this definitely puts his status up in the air. If McKinnon is not good to go, the 49ers will have Alfred Morris as a sure thing and possibly Matt Breida if his shoulder injury is healed.
We’ll update this when we know more about the extent of the injury.
