Greenlaw’s injury happened after a San Francisco punt with 9:26 left in the second quarter. Greenlaw was not on the field for the punt and was simply running back onto the field for the next defensive series when he went down after taking a step toward the field.
It was a noncontact injury, and though Greenlaw was able to hobble to the sideline, he was quickly taken to the locker room on a cart and was in tears, according to the CBS broadcast.
Greenlaw had three tackles before his injury. Oren Burks replaced him at weakside linebacker.
Later, with 9:10 remaining in the third quarter, Deebo Samuel was shaken up. But San Francisco’s standout receiver was able to walk off under his own power.
