After rumors of a possible trade for a wide receiver, the Miami Dolphins have found their man off the waiver wire, acquiring Anthony Armstrong from the Washington Redskins (via Sun Sentinel).

The move will save the Dolphins from having to give up a late pick for Armstrong, and it allows them to keep their ammunition if they feel the need to bring in an additional wide receiver as well.

With the Redskins, Armstrong managed only seven receptions last season, but had 44 catches and 871 yards back in 2010.

In 2008, Armstrong was actually a member of the Dolphins' practice squad, but was waived just weeks before the 2009 season.

In a very weak group of Dolphins receivers, Armstrong should play a relatively big role, but that's not to say he'll come in and completely save the receiving situation.

Armstrong has a chance to start out wide alongside Brian Hartline, ahead of Legedu Naanee and with Davone Bess playing in the slot.

At the very least, Armstrong is an upgrade over Marlon Moore and Rishard Matthews.

A few other veteran wideouts—including Donte Stallworth—were brought in for workouts by the Dolphins over the last few days (via The Palm Beach Post), but it appears they have chosen Armstrong instead.

James Jones of the Packers is another name that has been mentioned—this time with a trade in mind—but the signing of Armstrong could end any discussions there.

Along with Armstrong, the Dolphins also made a few more claims on the waiver wire, including defensive backs Troy Nolan and RJ Stanford.

Among the casualties so far—those who need to be cut in order to get the roster back down to 53—are Steve Slaton and Tyrone Culver, two of the Dolphins' better backups at their respective positions.
