Randall Cobb and Geronimo Allison were surprise participants in practice after indications were they would both be in the rehab group because of their hamstring injuries. They even took some reps in the 11-on-11 unit drill.
It seems that Allison's concussion is no longer his primary concern. If Thursday's practice went well for the pair of pass catchers, it puts them on track to play Monday night. If that comes to pass, look for Cobb to enter the WR2/3 conversation with Allison more of a WR3/4. Keep an eye on Friday's practice reports for more information.
