His replacement, Michael Chopra, scored City's 2nd goal. Chopra himsaelf was unwell prior to the game but he's fine now and will start at Burnley tonight.
Dave Jones said: "Chops is back to his best. He's fine.
"He was dehydrated and we gambled by putting him on the bench against Preston, but it paid off because he scored."
It's hoped McCormack will be fit for when Chopra's loan spell ends at the end of the month.
