Moore underwent surgery for a Lis Franc injury to his left foot sustained in the preseason opener against Tampa Bay, and will be in a protective booth for another month.
The Dolphins have yet to put Moore on injured reserve, but Wannstedt said that had more to do with wanting until the last possible second to make a move.
One way or another, it's a frustrating period for Moore.
"I can't tell exactly what happened," said Moore, who was injured while covering a kickoff. "It's pretty frustrating. I came out for my first game and was really excited, but I never got the chance to even take a snap on defense."
