Carroll (concussion) was a full participant at the Cowboys' practice Wednesday, David Helman of the Cowboys' official site reports.

EDGE Analysis

Carroll has missed the last two games after sustaining the concussion Week 3. It's certainly a step in the right direction for the 30-year-old, but Clarence E. Hill Jr. of the Fort Worth Star-Telegram indicates Carroll has yet to fully clear the league's concussion protocol, and his status for Sunday's game against the Packers remains uncertain.
