User blog:Nitaro/CC bars?

As some of you probably noticed in the last 2 champion spotlights (that being Sejuani's and Trundle's remake)every time a champion is effected by a crowd control effect,there seems to be a white bar that appears underneath the mana bar,which i think indicates the duration of the CC effect.Now thats just my theory since i dont know  for sure what exactly it is.So i would like to ask you ladies and gents...does anyone has any official info on those bars or are we just gonna look at them in patch previews and Champion spotlights?Any info is apritiated regardless  if it is official or not,theroies are also welcomed.

PS. Grammar nazis are not apritiated and i have the excuse of English language being not my mother language.
