Sunday went from bad to worse for the Detroit Lions when quarterback Matthew Stafford suffered an injury on their final offensive play of the game. He scrambled to the left to avoid pressure and went down awkwardly after throwing a pass. An Atlanta Falcons defender fell on his ankle, which appeared to be rolled.

Stafford received treatment on the sideline and limped off the field after the game was over. It's clear something is wrong, but what specifically is not currently known. To get to the bottom of it, the Lions have scheduled an MRI on Monday, according to both FOX Sports' Jay Glazer and Pro Football Talk's Mike Florio.

Matthew Stafford suffered a right leg injury late in Sunday’s loss to the Falcons.  Per a source with knowledge of the situation, Stafford will have an MRI to examine whether and to what extent he has damage to his knee and ankle.

Glazer reported that Stafford was in a walking boot following Sunday's game. That makes it seem unlikely he will be able to play next Sunday against the Denver Broncos, but then again, until he has the MRI it's probably not even worth speculating about.
