Live from (soggy) Sun Life Stadium

MIAMI, Fla. -- The Dolphins return home Friday night for their third and most important preseason game of the summer. The AFC East blog is here to take in all the action between Miami and the Atlanta Falcons.

Rookie quarterback Ryan Tannehill will get his second NFL start, and we will be monitoring his progress. It's very wet here at the stadium, so we will see if the rookie can handle the conditions. We are also curious about the new 4-3 defense, and whether it will improve from the first two weeks.

We will have a full report later tonight in the AFC East blog. You can also check out live, in-game updates and injury news by following me on Twitter here.
