Tillman, Brown set to practice Thursday

The NFL statement on the new measures went as followed:

"Once removed for the duration of a practice or game, the player should not be considered for return-to-football activities until he is fully asymptomatic, both at rest and after exertion, has a normal neurological examination, normal neuropsychological testing, and has been cleared to return by both his team physician(s) and the independent neurological consultant. A critical element of managing concussions is candid reporting by players of their symptoms following an injury. Accordingly, players are to be encouraged to be candid with team medical staffs and fully disclose any signs or symptoms that may be associated with a concussion."

As for Brown, he sat out Wednesday's practice as well while nursing a bruised right calf. It remains unclear whether Tillman or Brown will be limited or full go Thursday, but having them back on the practice field is a good sign in preparation for Sunday's game against the Rams.

Linebacker Lance Briggs (knee, hip) and Pace (groin) are expected to be sidelined for the second straight day Thursday.
