"He talked with the doctors, and they told him that it was better to hold off," Wannstedt said. "They also encouraged him to have the MRI just as a precaution to make sure everything was OK."
The setback was a big disappointment for everyone because Gardener seemed to have fully come back from the back problem that required surgery last September. In fact, Gardener talked last week about being ready to have a "monster year."
The Dolphins have good depth at the defensive tackle position, thanks to backups Jermaine Haley, Ernest Grant and Damian Gregory, but none of those players has Gardener's ability to dominate at the line of scrimmage.
There has been no word on how much, if any, time Gardener will miss because of his latest back problem.
Rest assured the Dolphins are keeping their fingers crossed.
