Miami Dolphins quarterback Ryan Tannehill will have surgery to repair the torn anterior cruciate ligament in his left knee and will miss the entire season, according to multiple sources, although the team has not made an announcement.
The Associated Press, ESPN and the Miami Herald, which first reported the news, say Tannehill will be placed on injured reserve.
Tannehill, who missed the final four games of last season with two sprained ligaments in his knee, reinjured it a week into training camp on Aug. 3. The Dolphins consulted with specialists before deciding surgery was the best option.
Jay Cutler, who parted with the Chicago Bears after eight seasons, agreed to delay his fledgling network TV career and signed a $10-million, one-year contract Monday to possibly replace Tannehill.
Cutler, 34, had planned to be a game analyst for Fox this fall. He was 68-71 as a starter with a career quarterback rating of 85.7, 208 touchdown passes and 146 interceptions.
Matt Moore, the former Hart High and Oregon State standout who turns 33 next week had been Tannehill's backup. He helped the Dolphins clinch their first postseason berth since 2008, going 2-1 as a starter to end the regular season before a first-round playoff loss at Pittsburgh.
