Thomas was one of many key injuries the 49ers had Sunday. Safety Jimmie Ward fractured his forearm. Left tackle Joe Staley was taken to the hospital to have his orbital bone examined.

Right tackle Garry Gilliam exited in the first half with a leg injury. Rookie nose tackle D.J. Jones departed with a knee injury. Receiver Pierre Garçon left the game in the second half with a neck injury.

The defensive line was a bright spot Sunday, while the 49ers held the Eagles to 304 yards of offense, averaging just 4.6 yards per play. Leger Douzable had two sacks, and nose tackle Earl Mitchell also added one.

Sunday the 49ers return home to play the Cardinals. Third-year player Ronald Blair will be eligible to return from injured reserve after a wrist/hand injury from August.
