Kansas City Chiefs running back Jamaal Charles left Thursday night’s game against the San Diego Chargers midway through the fourth quarter after taking a helmet-to-helmet hit from Chargers linebacker Donald Butler.
Charles had caught a pass over the middle from quarterback Matt Cassell and fought through a tackle by Chargers defensive back Corey Lynch. As he slipped through the attempted tackle, Charles fell backward as Butler came in on Charles from behind. They hit helmet-to-helmet and Charles remained down on the field.
Charles was attended to before walking off under his own power.
UPDATE 12:35 a.m. ET: Charles officially left the game with a neck injury. According to Adam Teicher of the Kansas City Star, Charles said he felt he could have gone back in but was told he was done for the night.
