Trey Lance fractured his right ankle in the first quarter of the 49ers’ home-opening win over the Seahawks, and the upstart quarterback required a cart to take him into the locker room for further evaluation.
Coach Kyle Shanahan confirmed after the game that Lance had broken his ankle and would require season-ending surgery.
The 49ers’ medical staff appeared to place an air cast on Lance’s leg following a collision with linebacker Cody Barton.
