UPDATE: Tannehill has a hyper-extended knee and deep thigh bruise, according to Miami Herald columnist Armando Salguero. He will undergo an MRI on Monday.

Rookie quarterback Ryan Tannehill left the Dolphins game against the Jets with a leg injury after a sack from Calvin Pace.

Tannehill has started all seven games for Miami this season after being selected in the first round (eighth overall) by the Dolphins in the 2012 draft.  On the day, he had completed two passes in five attempts for 18 yards.

Matt Moore, who played in 13 games for the Dolphins in 2011, is now in at quarterback.
