Chicago Bears safety Jaquan Brisker has entered the concussion protocol after self-reporting symptoms following the team's victory over the Carolina Panthers. He did not travel with the team to London for their upcoming game against the Jacksonville Jaguars. Brisker has a history of concussions and will need to pass the NFL's five-step protocol to play on Sunday. If he cannot play, backup safety Elijah Hicks is expected to step in.

• Brisker is a key player for the Bears' defense and his absence could impact their performance against the Jaguars.
• This is Brisker's third concussion in three seasons, raising concerns about his long-term health.
