NFL injury report: Lions' Jeff Backus goes down

The Detroit Lions weren't able to secure a victory over the Green Bay Packers on Sunday, nor were they able to escape without injuries. Left tackle Jeff Backus left the game late in the first half with a hamstring injury. He did not return, and was replaced by rookie Riley Reiff.

Reiff has received a good deal of playing time this season as an extra blocker, and fans have been clamoring for him to get a starting position. Still, this isn't the way the Lions hoped he would have been pushed into a starting role. It's unclear how serious the injury is, but the Lions have a short week with a game on Thursday Night Football, so that really hurts his chances of returning.

That was the only significant injury that occurred in the game. On Saturday, safety Amari Spievey was placed on injured reserve, and fellow safety Louis Delmas missed his third straight game. Defensive tackle Corey Williams missed his second straight game.
