The Washington Redskins and New Orleans Saints have agreed on a deal for Pro Bowl offensive tackle Jammal Brown, according to a team source.

The trade is subject to a physical. Brown flew to Washington mid-afternoon Saturday, and is scheduled to undergo the physical later in the day.

The Saints' compensation is actually tied to the Redskins' trade with the Eagles for quarterback Donovan McNabb.

After Saturday's trade for Brown, Washington will be without its third- and fourth-round picks in 2011, but it also will be getting back a later pick from New Orleans, according to a league source.

Washington owes the Eagles a third- or fourth-round pick in 2011 for McNabb, based on how the quarterback plays or the team performs. If the Redskins win nine games, or go to the playoffs, or McNabb gets selected to the Pro Bowl, then Philadelphia will receive Washington's third-round pick and New Orleans will get Washington's fourth. If none of those happen, then the Eagles will get the Redskins' fourth-round pick and the Saints will get the Redskins' third-round pick.

If Washington's third-round pick goes to Philadelphia, then the Redskins' fourth-round pick will go to New Orleans, with a sixth- or seventh-round pick coming back to Washington from the Saints. However, if Washington's fourth-round pick goes to Philadelphia, then the Redskins' third-round pick will go to New Orleans, with a fifth-round pick coming back to Washington from the Saints.

There is also a conditional 2012 sixth-round pick involved. Should he play 90 percent of the plays next season or get voted to the Pro Bowl, then Washington will send its 2012 sixth-round pick to New Orleans. After Saturday's trade, Washington has six picks left in the 2011 draft.

If everything goes through, the Redskins will have options at offensive tackle. Brown and first-round pick Trent Williams can play either tackle position. But the initial plan is to have Williams at left and Brown at right.

Brown has only one year remaining on his contract. The Redskins have no plans in place to sign Brown to a long-term extension yet, but they ultimately plan to keep him.
