After the roster cutdown, it was reported that David Martin was waived/injured, and Davon Drew was signed.
The next day, it was reported that Martin was actually on IR. Its possible that Martin didn't accept the injury settlement, in which case under the CBA this is what might have happened.
Then today, we find out that Davon Drew was waived/injured and the Dolphins signed Andrew Gardner (T) off the practice squad.
Weird things can happen in 3 days, can't they??
