On June 1st, after having to move Peyton and Eli to a different job, Brady was on site at the Peace Cross doing some power washing. He was on the scaffold properly (which means he followed all safety precautions and requirements) when one of the poles holding it in place snapped. This caused Brady to fall 15 feet, landing on his right arm. Though he wasn't badly hurt, it would sideline him for several weeks. He wouldn't be able to assist with finishing the Peace Cross project; participating in the local charity football game in August; and, possibly, prevent him from taking on additional work for the company. It turns out that the company who owned and who installed the scaffolding did not properly fasten the poles together. This wasn't a case of improper design; the errors came from the company who set up the scaffolding for Brady.
