For weeks, Shaun Alexander's cast has been getting more attention than his running. "The cast is a great fashion statement - but I am already ready for it to end," the Seahawks' star running back said Thursday, three days before he plays for the fourth game with a cast protecting his cracked left wrist, Sunday at Pittsburgh (3-1). "I know I'm healing at an incredible rate," he said with a chuckle. "All the doctors are amazed with how well I healed." Alexander said he will probably get a third X-ray on the wrist following the game against the Steelers. Alexander said it's taken him time to get used to running with the cast. And he has dropped passes trying to catch them with his good arm.
