We've had a couple of potentially significant injuries Sunday afternoon in the NFC North.
First, Detroit Lions punter Ben Graham suffered a calf injury during the Tennessee Titans' trick-play punt return for a touchdown. Place-kicker Jason Hanson has replaced him and got off a 37-yard effort on his first attempt. Backup quarterback Shaun Hill will probably take Graham's spot as the holder in a game the Lions currently trail 17-6.
Meanwhile, the Minnesota Vikings have lost safety Mistral Raymond to what appears to be a right ankle injury, one that was serious enough to be immediately placed in an air cast before he was carted off the field. You hate to see any injury, but especially a noncontact version like Raymond's. It appeared his right foot got stuck in the Metrodome's in-fill surface as he tried to chase San Francisco 49ers running back Frank Gore.
Raymond has been replaced in the lineup by Jamarca Sanford. At the moment, the Vikings hold a 7-3 lead over the heavily-favored 49ers.
