Report: Lions QB Matthew Stafford has fractured back, will not play vs. Bears

But the question is, how long will Stafford be out of action?

According to ESPN insider Adam Schefter, Stafford is considered week to week and he could be out up to three weeks or as little as just one week.

From ESPN:

“Stafford was practicing Friday and throwing 60-yard passes, but doctors wanted him to have further testing on this painful back injury, according to multiple sources.

Stafford is now considered week to week with an injury that one source said could sideline him for “this week or 3 weeks.” Stafford had started 136 consecutive regular-season games entering Sunday, the sixth-longest streak for a quarterback in NFL history.”

With Stafford out, backup QB Jeff Driskel will take over for the Lions.
