Scratch McCargo from Colts after failed physical

Posted by ESPN.com's Paul Kuharsky
It turns out the Colts are going to have to make do with what they've got on their interior defensive line.

John McCargo failed his physical after the Buffalo Bills traded him to Indianapolis. He's got a herniated disc in his back.

Early Wednesday, Tony Dungy spoke optimistically about working McCargo into Sunday's game in Green Bay.

They'll have to stop Ryan Grant, who ran a career-high 33 times in last week's win over Seattle, without him.
