DeSean Jackson is officially a Washington Redskin. We know that because he signed his contract on Tuesday afternoon.

Now the next question is: What number will Jackson wear in Washington? And that question isn't as easy to answer as it might seem.

Since his rookie year in 2008, Jackson has worn No. 10. There's a small problem with getting that number in Washington though: It's already taken. And it's taken by someone who Jackson probably won't be able to buy off. That someone would be Robert Griffin III.

Even though RG3 has worn No. 10 since high school, Jackson is still holding out hope that the Redskins quarterback will give the number up, "We talked about it," Jackson said on Tuesday, via ESPN.com. "That hasn't been a decision that's been made. Maybe RG3 will wear No. 3. You never know."
