Joe DeCamillis showed up Tuesday for the first day of organized team activities, wearing a neck brace but walking around among the players. He was released from the hospital May 10, just eight days after getting hurt.
The 43-year-old DeCamillis was carrying coaching notes as he made his way around the team's temporary practice facility with another assistant coach.
DeCamillis was one of 12 people hurt when the tentlike structure collapsed during a storm.
Team scouting assistant Rich Behm was paralyzed from the waist down in the accident but recently told coach Wade Phillips that he is looking forward to returning to work.
