Dolphins EDGE Chop Robinson suffered a concussion in Miami’s Week 9 game against the Ravens and will not return.

The second-year first-rounder went down at the midway point of the first half and was ruled out just before the break. He should be considered week to week, though he has 10 days to get cleared for Week 10 against the Bills. The 22-year-old is in the midst of a disappointing sophomore campaign, registering only one sack and eight hurries thus far.
