Ryan Tannehill hurts knee vs. Bills

ORCHARD PARK, N.Y. -- Miami Dolphins starting quarterback Ryan Tannehill left Sunday's game against the Buffalo Bills with a knee injury but returned to the contest.

Dolphins backup Matt Moore replaced Tannehill in the fourth quarter.

But after Moore was intercepted, Tannehill returned to the game later in the quarter.

The Bills sacked Tannehill six times in the game, and the final sack forced the quarterback to limp to the sidelines.
