The Minnesota Vikings will receive an additional draft pick -- in the seventh round -- from the Philadelphia Eagles if they advance to the NFC Championship Game as one more condition attached to the summer trade of quarterback Sam Bradford, according to league sources.

The announced deal had the Eagles receiving the Vikings' first-round draft pick in 2017, as well as a conditional fourth-rounder in 2018 in exchange for Bradford. It also stipulated that if the Vikings reach the NFC Championship Game this season, the conditional fourth-round pick in 2018 would become a third-round pick.

It has been learned that if the conditional fourth-round draft pick the Vikings sent to Eagles turns into a third-round pick, Philadelphia also would have to send a seventh-round pick back to Minnesota.

So while most thought the trade was Bradford for a first- and conditional fourth-round pick, the Vikings also could be getting back Philadelphia's seventh-round draft pick, and the blockbuster trade of the summer could involve one more pick than most realized.
