Miami began trimming toward the 53-man roster, waiving Aaron Shampklin as Mike Boone’s preseason edge stood out. Boone’s two exhibition appearances included a 7-yard TD against Jacksonville, while Alexander Mattison’s season-ending neck injury opened backfield vacancy that Miami shuffled to fill with Boone and Shampklin on Aug. 11. With Jaylen Wright’s health uncertain and more cuts anticipated Monday, fantasy managers should monitor the depth chart for Week 1 and potential RB-by-committee shifts.
