While a match between Brock Lesnar and The Undertaker has been discussed for WrestleMania 30, there is growing concern that a number of factors could prevent the match from taking place.
A big concern is that Brock Lesnar's very physical style would not pair well with a limited Undertaker, who would of course be entering the match banged up physically. This is why WWE officials originally considered Sheamus as 'Taker's opponent.
Another key issue is that many of Undertaker's opponents over the course of the past couple years have planned their bouts with 'Taker in detail, and have practiced the matches with him leading up to the PPV. There has been concern that Lesnar would be unwilling to put that much time into preparing a match.
