The Dolphins can take some solace that they haven't lost any core players, but it doesn't change the fact that they've had to deal with more than share of setbacks in recent weeks. It started with the sudden retirement of Jason Ferguson in mid-July and continued Wednesday with the injury sustained by running back/kick returner Kory Sheets.
Sheets sustained an Achilles tendon injury and he'll be lost for the season. He was considered a long shot to make the roster, but was among the contenders to win the kickoff returner job.
Also on Wednesday, Coach Tony Sparano revealed that rookie free agent cornerback A.J. Wallace had left the team. He was even more of a long shot to make the team than Sheets.
The other losses, of course, involve rookie linebacker A.J. Edds (torn ACL) and defensive end Phillip Merling (torn Achilles).
The Dolphins can only hope they're already exhausted their quota of major injuries this summer.
