The Miami Dolphins activated Xavien Howard from the COVID-19 and the Physically Unable to Perform lists on Thursday, allowing the cornerback to get on the practice field for the first time this summer. Howard has been recovering from offseason knee surgery, a procedure that forced him to start the year on the PUP. He was added to the COVID-19 list, a designation that indicates either the player tested positive for coronavirus or was near someone who tested positive, two weeks ago. He was the last Dolphins player remaining on the list.
