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

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 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.
