Matthew Stafford did not have X-rays or an MRI performed at Soldier Field on Sunday but it appears the team expects him to miss two-to-three weeks at a minimum.
According to Pro Football Talk:
A source close to Stafford describes the team’s concern as “all speculation at this point.” X-rays were not taken at the game because the Lions had no access to a machine at Soldier Field. X-rays and an MRI will be performed in the morning.
