The Packers lost receiver Randall Cobb to a shoulder injury, while Eagles quarterback Sam Bradford threw three touchdowns passes in Philadelphia's 39-26 win over Green Bay on Saturday night.
Bradford was 10 of 10 for 121 yards before giving way to backup Mark Sanchez in the second quarter for Philadelphia (3-0).
Acquired in the offseason from St. Louis, Bradford is coming back from tearing his left ACL twice in a 10-month span while with the Rams.
The Packers (1-2) keep losing players.
Cobb left after landing on his right arm while trying to catch a pass near the sideline on Green Bay's first offensive series.
He is the second Packers starting wideout to get hurt in the preseason. Jordy Nelson was lost for the season with a right knee injury last Sunday against Pittsburgh.
Starting quarterback Aaron Rodgers didn't play.
