Jamaal Charles injured his foot moving out of the Chiefs’ dorms

Chiefs head coach Andy Reid revealed that running back Jamaal Charles injured his foot while moving out the team’s dorms at the end of training camp.

“He came down a grassy slope there and just kind of rolled his foot over on the curb,” Reid said, via ESPN.com. “It was that simple. That was it. He went up to [trainer Rick Burkholder]. … He was hurting that night, and the next day he woke up and he was feeling a little bit better, and he’s feeling better today.

“We’re optimistic about it. Initially there was some concern. He had all the stuff done on it, the X-rays, the MRIs and all that done on it. Everything is clear.”

Charles was held out of this past Sunday night’s preseason game against the Panthers.
