Eagles QB Young doubtful for Sunday

Eagles quarterback Vince Young is listed as doubtful with a hamstring injury for Sunday's season opener at St. Louis.

Young was hurt during the final preseason game against the New York Jets last Thursday night. He pulled up lame while scrambling on the right side late in the second quarter. Michael Vick's backup was untouched on the play, throwing an incomplete pass.

The former Titan signed a one-year contract to play behind Vick.
