The Republic of Ireland international struck in the 72nd minute to cancel out Adam Hammill's first-half thunderbolt but Nigel Pearson's side languish at the wrong end of the table and Kilbane believes they should be doing better.
He said: "We've gone back into the dressing room after the game and although we played well in the second half, one or two of the lads were talking to each other in a harsh way because that is the reality of the game.
"We've got to be on at each other because we've got good players, but we've been under-performing."
