Giants head coach John Harbaugh said Brian Burns sustained a low ankle sprain in Week 2 against the Rams.

Burns was among the key Giants who went down with injury in a blowout loss to the Rams. Burns suffered the sprain in the fourth quarter and needed help getting to the sideline. Harbaugh said the team diagnosed Burns with a low ankle sprain. That could mean he won’t miss much time. New York’s defense, which has struggled through two games — giving up the NFL’s fourth highest offensive success rate — could be even more vulnerable without Burns in the lineup.
