RB suffers early shoulder injury

IRVING, Texas -- Arizona running back Emmitt Smith had his first game as an opponent of the Dallas Cowboys cut short because of a sprained left shoulder, and finished with the least productive game of his career.

Smith, the NFL's career rushing leader, left early in the second
quarter. X-rays on his shoulder were negative, but Smith remained
in the locker room after halftime and team officials said he would
not return.

The homecoming ended with Smith losing 1 yard on six carries. He
also caught two passes for 2 yards.

Smith was hit hard every time he touched the ball, and was
crushed at the line by Cowboys safety Roy Williams on his last
carry. On the game's first play, Smith was buried in the backfield
by defensive tackle La'Roi Glover for a 4-yard loss.

Smith signed with the Cardinals last spring after being released
by the Cowboys. He spent 13 seasons in Dallas, breaking Walter
Payton's rushing mark last October, and was part of three Super
Bowl championships.

Dallas offensive guard Larry Allen, a seven-time Pro Bowler
while blocking for Smith, left the game late in the first half with
a sprained left knee.
