Source: Rodger Saffold sprains neck

DETROIT -- St. Louis Rams offensive tackle Rodger Saffold has movement in his arms and legs after being carted off the field with a neck injury in the fourth quarter of Sunday's game against the Detroit Lions.

A league source told ESPN NFL Insider Adam Schefter that Saffold has a sprained neck.

Saffold crumpled awkwardly after disengaging from Lions safety John Wendling on a long St. Louis pass. The Rams scored a touchdown on the play to take a 20-13 lead with 9:45 remaining.

Saffold remained down for several minutes, and some Rams players held hands and formed a prayer circle on their sideline. Saffold was eventually lifted onto the cart but did not appear to be moving much. But coach Jeff Fisher said after the game Saffold had movement in his limbs and would undergo a CT scan.

The 6-foot-5, 314-pound Saffold is in his third season with the Rams. He started nine games last season after starting 16 as a rookie.
