The Eagles placed Considine, a third-year veteran, on injured reserve Wednesday. He started all eight games and had 47 tackles, one interception and a pass defensed.
To replace Considine on the roster, Philadelphia elevated rookie safety Marcus Paschal from its practice squad. It is not yet certain who will replace Considine in the starting lineup. Quintin Mikell, who started at free safety while Brian Dawkins recovered from a neck injury, is a possibility.
Considine, 26, has played well since moving into the starting lineup in 2006. Viewed as a bit undersized but aggressive and a solid hitter, the former Iowa Hawkeye bulked up during the offseason.
After starting his career as a special teams player, Considine progressed quickly and his aggressive play and nose for the ball earned him increased playing time and, eventually, the starting job.
The Eagles are confident the shoulder injury should not pose any long-term problems for Considine, a fourth-round choice in the 2005 draft.
In 30 games, including eight starts, Considine has 154 tackles, two interceptions, six passes defensed, 1½ sacks, one forced fumble and two recoveries.
