Carroll (leg) has agreed to re-sign with the Eagles on a one-year contract, ESPN reports.
Carroll started the first 11 games of last season before suffering a broken fibula in a Thanksgiving loss to the Lions. He may have to compete for a starting job in 2016, as the Eagles traded away Byron Maxwell but did sign Leodis McKelvin. 2015 second-round selection Eric Rowe also figures to compete for a starting spot on the outside.
Brooks (neck) was placed on injured reserve Tuesday.
Neck and shoulder issues cost Brooks time recently, even forcing him into the concussion protocol, though it's not entirely clear whether his placement on IR is related or due to a new injury. Brooks played primarily on special teams this season, recording 12 total tackles (11 solo).
Foster (Achilles) is expected to be healthy for training camp, should he sign with a team, Jeremy Fowler of ESPN.com reports.
Foster was released by Houston, his home for the past seven seasons, earlier in the offseason after another disappointing year plagued by injuries. Currently unemployed, he continues to rehab from a torn Achilles in the hopes of finding his way onto a roster. Reports say the four-time Pro Bowler will be hungry and healthy for training camp should any team bring him on.
