Seth Rollins tweets about The Undertaker

Last week on RAW, The Shield attacked John Cena. And Seth Rollins’ recent tweet looks like a warning to The Undertaker. Are The Shield looking to attack The Undertaker on tonight’s RAW?

Here is Seth Rollins’ tweet about The Undertaker:

“Deadman” is quite the poetic alias, wouldn’t you say? …The Hounds invade O2 tonight. And our teeth are like daggers. #RAW
