The Jets' great start to free agency has taken a hit early Tuesday afternoon.
After reaching a deal with Gang Green Monday evening, Vikings linebacker Anthony Barr has backed out of the agreement, according to the NFL Network's Mike Garafolo.
Monday was the first day of the league's legal tampering period. Contracts cannot be signed until Wednesday. The Jets entered free agency with more than $82 million available under the salary cap.
