KANSAS CITY, Mo. -- In a post on his blog, Jamaal Charles revealed some of the details about the knee injury that ended his season back in October after only three games.

The Kansas City Chiefs running back wrote that the injury, a torn meniscus, happened not during a game or even practice but during a post-practice session shortly after his most productive game of the season, on Oct. 16 against the Oakland Raiders.

“There’s been speculation that I tried to come back too quick, or that I wasn’t ready, but I honestly don’t think me coming back to play is what caused this to happen." Charles wrote. “I think, if anything, I was doing too much extra work on top of what I was doing with the team and the trainers."
