WrestleMania 30 Rumors:: Undertaker vs. Lesnar Match in Question? Sheamus To Take Brock's Place?

It has been rumored for months that Brock Lesnar will take on The Undertaker and his undefeated streak at WrestleMania XXX on Sunday, April 6 live from the Mercedes-Benz Superdome in New Orleans, but new reports indicate that there may be some doubt within the WWE that the match can happen due to Undertaker's declining health, and Sheamus may be a replacement.
