Ruptured tendon may sideline Eagles' Jackson for the season

PHILADELPHIA (Reuters) - Philadelphia Eagles safety Marlin Jackson has a ruptured Achilles tendon and could miss the upcoming season, the team said.

Jackson suffered the injury to his right leg during workouts on Tuesday, the Eagles said on their website (http://www.philadelphiaeagles.com).

A former first-round draft pick, Jackson was acquired by the Eagles during the off-season after spending five years with the Indianapolis Colts. He started at both safety and cornerback for the Colts.
