Minnesota Vikings running back Adrian Peterson had an MRI scheduled for Monday on his injured ankle, and head coach Leslie Frazier spoke about the injury and the results of the MRI to the media on Monday. According to the Pioneer Press, Frazier said that it's a grade 1 high ankle sprain, and that Peterson will wear a boot for a few days. The tweet also notes that Peterson "might" start light football activity as early as Friday.
Given this news, it seems as though Peterson's status on Sunday against the Atlanta Falcons is in doubt, though the running back himself thinks that it won't be an issue. Peterson said that he'd be ready to play this weekend and that it wasn't "in his DNA" to miss time with an ankle sprain, even before he knew the severity of it.
Last year, Peterson had a high ankle sprain and returned for the next week, rushing for over 100 yards and three touchdowns against the Bills. The important thing to note here is that's it's a sprain, and not a fracture.
