Dolphins' Mark Perry: Dealing with undisclosed injury

The Dolphins placed Perry (undisclosed) on the active/non-football injury list Tuesday.

Miami signed Perry as an undrafted free agent earlier in the offseason. The team can move him to the active roster at any point during training camp, but the safety won't be able to practice until that happens. If Perry remains on the NFI list beyond Aug. 27, he'll need to miss at least the first four games of the regular season.
