Seattle Seahawks nose tackle Brandon Mebane, who coach Pete Carroll said was having the best season of his career, is out for the season with a hamstring injury. The team placed Mebane on season-ending injured reserve Tuesday and signed tight end RaShaun Allen from the Vikings' practice squad to fill his roster spot. Mebane suffered a torn hamstring suffered in Sunday's game against the New York Giants. Mebane is deciding whether to have surgery, sources told ESPN's John Clayton. Without surgery, the recovery period would be a minimum of eight weeks. Mebane arguably was the best player on the Seahawks' defense this season with his play at the line of scrimmage, usually taking on two blockers and being a major factor in Seattle ranking fourth in rush defense, allowing only 79.8 yards per game. http://espn.go.com/nfl/story/_/id/11859589/brandon-mebane-seattle-seahawks-season-torn-hamstring
