Minnesota Vikings linebacker Anthony Barr continues to be sidelined with injury and his progress is a mystery so far.
Mike Zimmer and John Sullivan returned to practice for the Minnesota Vikings on Thursday, but linebacker Anthony Barr remains sidelined.
Zimmer returned after leaving camp on Monday to be with his ailing father, Bill, and Sullivan left Monday, too, to attend the birth of his first child, John Harris Sullivan.
Barr started to get back into the practice mix during minicamp after recovering from arthroscopic surgery in November that ended his season early, missing the final four games.
