Six-year veteran Idrees Bashir, the top backup at both safety positions for the Detroit Lions, will miss the rest of the season after tearing the anterior cruciate ligament of his right knee in Sunday's 16-10 loss to the New York Giants. Bashir, 28, was injured on the opening kickoff while attempting to make a tackle. The Lions placed him on injured reserve Monday afternoon, and he will undergo surgery in the next few weeks, when swelling in the knee subsides. The loss of Bashir, who missed the entire 2006 season because of a hand injury, is a key one for the Lions, because of his status as the No. 3 safety and his role in nickel packages, where he usually played in place of starting strong safety Kenoy Kennedy.
