49ers' Spencer Burford: Dealing with calf issue

Burford (calf) is awaiting an MRI on a calf injury, Matt Barrows of The Athletic reports.

Burford picked up a calf injury in Sunday's loss to the Dolphins and he's now awaiting an MRI to determine the extent of the injury. Burford stepped in at left tackle against Miami when Jaylon Moore (quadriceps) was forced to exit the game. Moore andAaron Banks (knee) both suffered season-ending injuries in the contest, while Trent Williams (ankle), who'd already missed the last four games, was ruled out for the final two games of the campaign Monday as well.
