Middle linebacker Stewart Bradley, back in action after missing last year with a torn anterior cruciate ligament, limped off the Eagles' practice field Wednesday and did not return, though the team downplayed his injury.
The Eagles said he had "tweaked" his calf. He pulled up during a seven-on-seven passing drill and limped to the sideline, where staff looked at his left leg, before leading him off the field. Bradley walked off without help, though he moved gingerly.
Bradley is expected to play a big part in strengthening the defense after the Eagles struggled to replace him last season. His injury, coming as he dropped into pass coverage during a drill, also came a day after the team lost safety Marlin Jackson to a ruptured Achilles tendon.
Bradley, too, was injured last year before the season began.
Joe Mays stepped into Bradley's role with the first team for the rest of practice Wednesday.
Bradley had been moving well. On Tuesday, he ran with tight end Brent Celek and broke up a pass when it came his way.
"Stew looks real good," Celek said. "He looks like his old self. I was telling him the other day that it doesn't look like he was ever injured at all."
Injury questions also surround the offensive line. Guard Todd Herremans missed another day of practice with a left foot injury. The Eagles have not provided details about the injury. Max Jean-Gilles has been filling in at Herreman's left guard spot.
Meanwhile, center Jamaal Jackson, who is recovering from a torn ACL in his left knee, said that he recently resumed running.
Jackson isn't expected to return to practice at least until after training camp. Nick Cole and Mike McGlynn have been splitting most of the first-team repetitions at center.
Former Eagles offensive lineman Shawn Andrews was selected in the third round of the United Football League draft by the expansion Omaha Nighthawks, according to the league's Twitter feed. It was unclear as of last night whether Andrews, who was released by the Eagles in March, would elect to play for the independent professional football league. . . . The Eagles signed running back Charles Scott, a sixth-round pick from Louisiana State, to a four-year contract.
