The Washington Redskins have agreed on compensation to trade veteran quarterback Donovan McNabb to the Minnesota Vikings.

Now, it’s a matter of seeing whether or not the Vikings can re-work McNabb’s contract to their suiting in order for the deal to go down, according to Jason La Canfora of NFL Network. That will require the Vikings to crunch some numbers with McNabb’s agent Fletcher Smith.

Otherwise, you could look at a scenario where the Redskins wind up having to dump McNabb. The Vikings probably will not be giving up much for the veteran quarterback. Some have speculated a seventh-round pick or a sixth at highest would get the deal done.

The Vikings don’t want to invest too much money in McNabb, either, not with Christian Ponder, their quarterback of the future in place.
