Jimmy Graham leaves Seattle Seahawks game with knee injury

Jimmy Graham has been taken for an X-ray on his knee after being carted off the field in the fourth quarter of the Seattle Seahawks' game against the Pittsburgh Steelers.

The tight end landed awkwardly on his right leg while trying to score a touchdown in the closely-fought contest at CenturyLink Field.

The 29-year-old, who had four catches for 75 yards in the game, was fitted with an air cast before being carted off the field.

Graham joined the Seahawks in an offseason trade with the New Orleans Saints.
