DuBose was claimed off waivers by the Dolphins at the end of August and appeared in a couple games early in the season before a shoulder injury sent him to injured reserve. Following the decision to part with Odell Beckham Jr., DuBose was activated and caught one pass Sunday before the injury.

“After sustaining a head injury in (Sunday’s) game, Grant DuBose remained at a local Houston hospital for evaluation overnight,” the Dolphins said in a statement released on social media. “He has movement in all extremities and initial tests have revealed positive results. He remains under the care of doctors for continued observation.”
