Sanchez went down at the beginning of Friday’s practice and was carted off the field to receive x-rays. Coach Carroll later informed the press corps that Sanchez dislocated his kneecap, will be immobile over the weekend, and then start physical therapy on Monday.
He is day-to-day but it is assumed (based on other players who've had this injury in the past) that he will be back in about 10 days—in plenty of time for the season opener at Virginia.
Don’t get too comfy there under center Mustain. My boy Mark will be back very soon.
