49ers coach Kyle Shanahan said Jake Tonges will undergo season-ending surgery to repair his torn MCL.
Tonges went down with the injury in Week 1. He filled in for George Kittle admirably last year and was likely going to play a role in the offense for the first month of this season as Kittle got up to full speed. He will now spend the rest of the season on injured reserve. Luke Farrell is now locked in as the 49ers’ TE2.
