Sources are reporting that veteran Washington Redskins quarterback Donovan McNabb will be traded to the Minnesota Vikings.

The Redskins are looking to receive fifth and seventh round picks, or perhaps two sixth round picks.

There may be contract problems that hold up this trade, though. McNabb had incentives in his contract under Washington, and may not make anywhere near the $14.75 million with the Vikings, according to ESPN.

The deal is not much of a surprise considering McNabb's benching at the end of the season by head coach Mike Shanahan, and the absence of a quarterback in Minnesota with the departure of Brett Favre and Tarvaris Jackson. 

The trade appears to be definite considered a recent tweet. First-round pick Christian Ponder wrote on Twitter: "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!"

The Vikings aren't the only team making deals. Seattle, who recently acquired Jackson and Matt Leinart, have officially lost Matt Hasselbeck, who has moved on to the Tennessee Titans.

Hasselbeck, 35, has reached a multiyear contract with Tennessee, and will serve as a mentor to Jake Locker, who is the team's quarterback of the future.

Expect plenty more deals in the next several days, as teams scramble to land free agents and make trades with preseason games looming.
