WWE.com can confirm that, following last's night historic match with Brock Lesnar, The Undertaker was immediately taken to Ochsner Medical Center. After a CT scan and other medical testing, he was diagnosed with a severe concussion and was kept overnight for further evaluation. He was discharged early Monday afternoon.

This would sort of explain why the match at WrestleMania why a good amount worse than anyone really expected. Also, Taj did say to Tim and in the Chatbox that he heard Brock tell Undertaker, "I will go easy on it" (before an F5), or something like that. Would explain why he would want to since Undertaker reportedly suffered the concussion very early in the match.
Really sucks for 'Taker but he needs to hang up the boots. He is injured after every single WrestleMania.
