KANSAS CITY — Richard Sherman walked out of the 49ers locker room in an orthopedic boot, doing so after a left-calf injury flared up and forced him out of Sunday’s 38-27 loss by halftime.
That was one of many sad sights among the 49ers defense against the high-scoring Chiefs.
Sherman will undergo an MRI on Monday on his lower leg, in which he had bone spurs removed this past winter; it was a torn right Achilles last November that ended his season and Seattle Seahawks tenure.
Sherman was part of a defensive-wide meltdown Sunday, exiting only after the Chiefs’ fourth touchdown drive in four series.
