The Dolphins and Tannehill were hoping his knee, with the aid of a brace, would be stable enough to last the season.
Miami Dolphins quarterback Ryan Tannehill will have reconstructive surgery on a partially torn ACL and miss the entire season, sources tell ESPN's Dan Graziano, confirming a Miami Herald report. With ir now being a recurring issue, Tannehill chose to get the knee fixed and try again in a year.
Gase and Tannehill seemed to develop a connection in 2016, but injuries are back-breaking in the National Football League and this could be a game-changer for the Dolphins.
Salguero said that the 29-year-old Tannehill is expected to undergo surgery sometime next week and will be placed on injured reserve with no chance to return later this season.
Tannehill suffered the non-contact injury last week while running toward the sideline during a drill. The Cutler signing signaled that this move was likely coming.More news: Guardiola unmoved by Manchester City favourite tag

Cutler's deal is for one season and it likely will remain that way.
Tannehill had the best year of his career in 2016 with the aid of Gase, who calls Miami's offensive plays.
Tannehill does have his flaws-including throwing at least 12 interceptions in each of his first five National Football League seasons-but he's had more positives than negatives throughout his career to this point.
Cutler will be the starter while Matt Moore retains backup duties. After Jay Ajayi landed in the concussion protocol program, rookie Raekwon McMillan tore his ACL during the preseason opening game.
Kickoff: Thursday, 7 p.m.; Hard Rock Stadium in Miami Gardens, Fla.
