The Miami Dolphins are placing superstar LT Terron Armstead on IR. He will be out for at least four weeks. Per the NFL Network, it is not expected to be a season-ending injury, but he may be out more than four weeks as well.

Once the Dolphins take Armstead off of IR, whenever that happens, there is a 21-day window for the team to move him to the active roster. Armstead got hurt in a joint practice in August with the Houston Texans. He was injured again last week in Buffalo.
