In the opening game of the 2008 NFL season, New England Patriots quarterback Tom Brady suffered a torn ACL (anterior cruciate ligament) and MCL (medial collateral ligament) in his left knee. ACL tears are common in sports and can be a significant setback. Brady underwent surgery and missed the entire season. He focused on rehabilitation and came back the following season to lead the Patriots to a successful campaign, showcasing his resilience and commitment to the sport.
