Dolphins' Adam Shaheen: Failed on physical, no trade

Shaheen has reverted back to the Dolphins after a failed physical voided a recent trade to Houston, Aaron Wilson of ProFootballNetwork.com reports.

Joe Schad of The Palm Beach Post notes that Shaheen was flagged for a preexisting knee condition, though he hasn't missed any time at Miami training camp. He doesn't seem likely to make the Dolphins' Week 1 roster and would've been battling for a back-end spot with the Texans.
