Bruce aired his frustration over the festive fixture list after three players were forced off in the defeat to the Foxes.
He said: “Asking players to play four games in 10 days is ludicrous and today is the consequence of that.
“I was concerned about the number of games but we could have lost five players today. Three of them are hamstrings and one [Jetro Willems] is a groin, while DeAndre Yedlin has broken his hand, we think.
“I didn’t have the bodies to make changes as we had four or five out anyway.”
