Patrick Mahomes suffered a torn anterior cruciate ligament in his left knee late in the Kansas City Chiefs' home game against the Los Angeles Chargers, an injury that ended the club's long playoff streak and will sideline him for the season.Coach Andy Reid said an MRI showed no major damage to other ligaments, and the team said Mahomes and club medical staff were exploring surgical options and a reconstruction and rehabilitation program that typically requires several months before a player returns to full competition.Backup quarterback Gardner Minshew will take over as the starter for the rest of the season, and the injury immediately reshapes Kansas City's offseason decisions, salary planning and play calling as the organization balances protecting Mahomes's future with keeping the team competitive.
