LINK NASHVILLE, Tenn. (AP) -- Tennessee quarterback Steve McNair will miss the final three games of the season and undergo surgery to strengthen the bruised sternum that has plagued him most of the year. Coach Jeff Fisher said they reached the decision Friday morning. Fisher said a chief consideration is that McNair, the NFL's co-MVP last season, will need the surgery even if he never plays football again to fix the damage caused by three injuries to his sternum. ``Basically, Steve does not have a solid bony surface throughout the length of his sternum,'' Fisher said. ``There's an area in there that's cartilage. It's not normal. He was born that way. And because of this area that's simply cartilage, when Steve suffered the first injury back in 2000, the sternum itself moved, creating a lot of pain and a lot of discomfort.''
