Dolphins' passing game in flux

As recently as three days ago, quarterback David Garrard and receiver Chad Johnson were expected to be the top passing duo for the Miami Dolphins.

How quickly things have changed.

Two unexpected events this weekend have put Miami's already questionable passing game further in flux. Garrard, who was winning the quarterback competition in training camp, decided to have surgery Saturday to fix wear and tear on his knee. He is expected to miss up to a month. And Johnson was arrested Saturday on charges of domestic violence.

Both incidents were unexpected. Both have set Miami’s passing game on its ear.

Garrard is no longer in the quarterback race. That much we know. The Dolphins are moving on with either Matt Moore or rookie Ryan Tannehill for Week 1 of the regular season.

But Johnson's future in Miami is more cloudy. He's has a one-year contract and is easy to release. But Johnson also has been the best receiver in Dolphins' camp. If the allegations are true, Johnson could be cut or facing a suspension by the league.

Without Garrard and possibly Johnson, there's even less confidence in Miami's passing game. Receiver Brian Hartline has been injured all throughout camp. Teammates Legedu Naanee and Davone Bess would have bigger roles than usual, and younger receivers Roberto Wallace and Julius Pruitt are unproven.

It's been an awful weekend for the Dolphins. Joe Philbin is an offensive-minded head coach, and he certainly has his work cut out for him.
