Some people (myself not included) believed that Kircus was going to make the roster, but he has been outplayed as of late by Anthony Armstrong and Greg Camarillo. There are now 7 receivers remaining in camp.
With Roberson's release, there are six cornerbacks left on the roster.
The first official cutdown day is Tuesday, when the NFL requires all rosters to be at 75 maximum, and then next Saturday rosters have to be trimmed to the final 53. Miami currently has 70 players on its roster.
