According to the Daily Racing Form:
Trainer Jimmy Jerkens said Friday that Quality Road was sore in his right front foot after training for three days, and has simply walked the shed since Wednesday. Jerkens said that an abscess, or pus pocket, popped out of the bulb of the colt's right front heel on Friday "to the inside of where the quarter crack is.''
Jerkens said that prior to the abscess popping, Quality Road had his shoes pulled to try and alleviate any soreness in his foot. Jerkens said the horse is getting treated with antibiotics.
Jerkens said Quality Road would not return to the track until next week and not until he gets new shoes and possibly a new patch on the quarter crack.
