The White Sox scratched Montgomery from the lineup for Sunday's game against the Rays due to a superficial skin infection on his right ankle, Scott Merkin of MLB.com reports.
The skin condition doesn't seem to be a major concern for Montgomery, but he'll effectively get two days to recover thanks to a team off day Monday. Everson Pereira will draw the start in right field in place of Montgomery, who is slashing .255/.339/.364 with zero home runs, one stolen base, eight RBI and seven runs in 15 games since the All-Star break.
