Chiefs running back Jamaal Charles had its most extensive playing time of the season at Oakland on Oct. 16. He logged nine rushing attempts for 33 yards and caught a pass for 14 yards. Although he had played the previous game in Pittsburgh, the effort against the Raiders seemed like the re-boot of Charles’ career after he missed more than half of last season because of a torn anterior cruciate ligament.
Turns out, the Oakland trip was the start of his trouble.
Charles had exploratory surgery on his right knee Wednesday by orthopedic surgeon James Andrews.
“It’s thought that he might have a meniscus tear in that knee,” Chiefs head athletic trainer Rick Burkholder said.
