Cardinals' J.J. Russell Injured, Released From Hospital

Arizona Cardinals linebacker J.J. Russell, age 26, suffered a head and neck injury during a 7-on-7 drill collision with rookie Kitan Crawford at Thursday's training camp, leading to immediate medical attention and his stabilization on a backboard before being carted off the field. Practice was halted and subsequently ended early as teammates expressed concern. Russell was transported to a local hospital, where thorough tests returned negative results. He was released from the hospital and rejoined the team at camp later that day. Russell, a recent free agent signee from the Tampa Bay Buccaneers, is valued for his special teams play and linebacker depth. The incident underscored the physical risks of NFL training camps and the league's increasing caution regarding head and neck injuries.
