3. By Philadelphia: Expands the "crown of helmet" foul to include "hairline" part of helmet.

4. By Philadelphia: Amends the challenge system by granting a third challenge if a club is successful on at least one of its initial two challenges, and expands reviewable plays outside of two minutes of each half.

5. By Washington: Eliminates the limit of three total challenges per team per game and eliminates the requirement that a team be successful on each of its first two challenges in order to be awarded a third challenge.
