In the history of WrestleMania, how many scheduled matches were cut?

Tatanka, The Smoking Gunns (Bart & Billy), Bob “Spark Plug” Holly and The 1-2-3 Kid vs. I.R.S., The Headshrinkers (Samu & Fatu), Rick Martel and Jeff Jarrett in a 10-Man Tag Team Match was supposed to take place at WrestleMania 10 and Tons of Funk (Brodus Clay & Tensai) & The Funkadactyls (Naomi & Cameron) vs. Team Rhodes Scholars (Damien Sandow & Cody Rhodes) & The Bella Twins (Nikki & Brie) in an 8-Person Mixed Tag Team Match was supposed to take place at WrestleMania 29. Both matches, however, ended up getting cut due to the time slots being overlapped by the previous matches. WWE ended up having both matches take place on Raw the following nights instead.
