A series of concussions have led to major questions about Tua Tagovailoa's NFL future, but the Miami Dolphins don't appear concerned.

General Manager Chris Grier insists there's no reason to be any more concerned about Tagovailoa than anyone else.

"From what our doctors and the consultants we've talked to through the NFLPA, that is not a true statement," Grier said. "So for us, I don't think he's any more prone than anyone else. For us, we're just letting the doctors, the medical staff and the people in that field that know more. From everything we’ve been told that is not a concern."
