The Miami Dolphins have placed quarterback Ryan Tannehill on injured reserve, according to the Dolphins’ official Twitter account. In a more minor move, they also signed linebacker Junior Sylvestre.
Tannehill will undergo season-ending knee surgery after tearing his ACL in the same knee that he had injured last season. The signal-caller re-injured himself in practice back on Aug. 3.
After Tannehill went down, Miami went out and signed retired quarterback Jay Cutler to take his place.
The 29-year-old Tannehill originally hurt his knee during the Dolphins’ Week 14 matchup with the Arizona Cardinals last year and proceeded to miss the final three games of the season as a result.
In 13 contests, the Big Spring, Tex., native threw for 2,995 yards, 19 touchdowns and 12 interceptions while completing 67.1 percent of his passes and registering a passer rating of 93.5.
Tannehill, who played his college football at Texas A&M University, was originally selected by Miami with the eighth overall pick of the 2012 NFL Draft.
He started all 16 games right out of the gate, finishing his rookie campaign with 3,294 yards, 12 touchdowns and 13 picks. He completed just 58.3 percent of his passes and recorded a passer rating of 76.3.
Tannehill made incremental improvements over the following couple of seasons, and in 2014, the 6-foot-4, 220-pounder had arguably his best year to date, piling up 4,045 yards, 27 touchdowns and 12 interceptions while completing 66.4 percent of his passes and posting a passer rating of 92.8.
Last season, the Dolphins made the playoffs for the first time since 2008, winning 10 games and ultimately falling to the Pittsburgh Steelers in the Wild Card Round.
