Chiefs' Bryan Cook Evaluated for Concussion, Texans' Al-Shaair Injured

Kansas City Chiefs safety Bryan Cook was evaluated for a concussion during the AFC divisional playoff game against the Houston Texans after suffering a head injury late in the first quarter while attempting a tackle. He exited the field for assessment in the medical tent and eventually walked to the locker room without his helmet. Cook, who had been a key player for the Chiefs, started all 17 regular-season games and was performing at a high level this season. Rookie Jaden Hicks replaced Cook in the lineup as the Chiefs navigated the impact of his potential absence. The team has not yet confirmed how long Cook might be sidelined, nor whether he will return during the current game. The situation is being closely monitored, with defensive coordinator Steve Spagnuolo considering adjustments to the secondary.
