Dolphins quarterback Ryan Tannehill is believed to have torn his ACL during the third quarter of Sunday's 26-23 victory over the Arizona Cardinals and is out for the remainder of the season, two sources with knowledge of the injury told NFL Network Insider Ian Rapoport and NFL Network's Courtney Fallon. He'll have an MRI to determine if there is other damage, Rapoport and Fallon added.

With an increased focus on the passing game in the last month, the Dolphins suddenly turn to a veteran who once threw for close to 2,500 yards and 16 touchdowns in 13 games under center in 2011 in Matt Moore. But at age 32, Moore is now a veteran backup at best, and he hadn't seen significant playing time since 2012 before entering the game. It could mean more focus on the run game with Jay Ajayi and perhaps Damien Williams.
