The Miami Dolphins’ first preseason game against the Chicago Bears at Soldier Field was marred by injuries and residual tension from last week’s joint practices. Running back Alexander Mattison exited in the first half after landing awkwardly on his head and is undergoing evaluation for a potential concussion. A Dolphins safety also left the game with an undisclosed injury. Head coach Mike McDaniel said post-game that medical staffs are still assessing both players and the club will provide updates when testing is complete. Off-field friction also followed the team to Chicago. McDaniel confirmed that linebackers Jordyn Brooks and Tyrel Dodson addressed the squad and apologized after their sideline scuffle during Friday’s combined practice with the Bears. The coach, who physically stepped in to halt multiple outbreaks during the session, called the incident “family business”—unwelcome but resolved. Both Brooks and Dodson stressed that the confrontation was “brotherly love,” and each played in Sunday’s exhibition without further incident.
