Fletcher Cox wasn't present when the Eagles began practice Thursday; the team's All-Pro defensive tackle has not taken the field since suffering a calf strain in the Sept. 24 victory over the Giants. He would seem unlikely to play this weekend against Arizona. The typical recovery time for an NFL calf injury is a little more than two seeks, according to a recent medical study.

Running back Wendell Smallwood was absent for the second successive day. A source with knowledge of the situation said Smallwood has knee swelling that isn't considered serious. Defensive tackle Tim Jernigan (heel) returned to the field Thursday after sitting out Wednesday.

Handling injuries this week is tricky, in that the Eagles play next Thursday at Carolina. A player who isn't 100 percent recovered probably isn't going to play two games in five days. After Carolina, the Eagles don't play until their home Monday night game against Washington, Oct. 23.
