The 49ers not only lost to the Chicago Bears on Sunday, but they also lost Elijah Mitchell for about two months. The running back was placed on injured reserve Tuesday.
Mitchell’s injury marks the second year in a row in which the 49ers have lost their starting running back in the first half of the season opener.
During his media conference call on Monday, Kyle Shanahan noted the injury to Mitchell came on an 11-yard run a few plays before Deebo Samuel scored the 49ers lone touchdown of the game.
With Mitchell sidelined, the 49ers will sign veteran running back Marlon Mack, per Adam Schefter of ESPN.
