Sources: Vikes have trade for McNabb

The Washington Redskins, Vikings and Donovan McNabb have a preliminary agreement in place for the veteran quarterback to be traded to Minnesota, sources told ESPN.

The compensation issues that were the stumbling blocks to the trade appear to be resolved.

The one sticking point now appears to be McNabb's concern Tuesday night about how the Vikings' side of the situation was handled. Sources said there were some in the organization who expressed a preference in acquiring quarterback Tyler Thigpen, who since has agreed to terms with the Buffalo Bills.

McNabb will be making far less than the $14.75 million he would have been due from the Redskins, but it is not clear how much he will be paid, and how any incentives would alter his compensation.

According to sources, the trade will involve a 2012 sixth-round draft pick and a conditional sixth-round pick for 2013 going to Washington. The Redskins had wanted fifth- and seventh-round picks from Minnesota.

Before the reporting of the deal, Christian Ponder, the quarterback drafted by the Vikings with the 12th overall pick in April, tweeted: "Excited to have McNabb join. Will learn a lot from a Pro Bowler. But that doesn't mean I'm not still fighting to start week 1!"

Redskins coach Mike Shanahan projects John Beck to be his starting quarterback this season. The team added depth to the position Wednesday, when it reached agreement on a one-year contract with Kellen Clemens, a league source told ESPN NFL Insider Adam Schefter.

Clemens, who spent five seasons with the Jets backing up Mark Sanchez, Brett Favre andChad Pennington, will compete to be the Redskins' No. 2 quarterback.
