Well... kind of. You'll note that there were only indirect references to any of the characters involved.
"One Noxian [murderer] even saw fit to destroy the poor tree, but he was restrained by the others – a sideshow far more entertaining than the match."
You'll note that no names were mentioned, in fact, Ryze and Kayle weren't even given mention in the article :P
In related news, Hotaru somehow managed to miss yet another person who would have wanted tea... then again, he'd have probably snubbed her (given his personality) for trying to serve him lukewarm tea.
