Charles had a procedure performed by Dr. James Andrews on November 14th. This time is was on his left knee. Chiefs’ head athletic trainer Rick Burkholder told the assembled press Thursday:
“He was having right and left knee pain. So, Monday, November 14, right after the Carolina game, Dr. Andrews operated on his other knee [left]. So he’s had his right knee scoped, and now, he’s had his left knee scoped. The rehab is the same, we anticipate recovery will be fine. We’ll see how it goes. Right now he’s still down at Dr. Andrews because he just got operated on, on Monday.
