Can a wild card play within the same division?

Three teams in the division can make it to the playoffs. 12 teams in total qualify for the playoffs, 6 in the AFC and 6 in the NFC. The division winners from each conference are the top 4 seeds. There are 4 divisions in each conference, so that's 8 teams. The remaining four make up the wild card teams. the next 2 best teams who are not division winners in the NFC and the next 2 best teams from the AFC also qualify for the playoffs, which are the 5 and 6 seeds. It is possible that both wildcard winners in either conference, are in the same division, as long as they have the next 2 best records.

Yes, in the 2006 playoffs, the Giants, Eagles, and Cowboys all made in from the NFC East.
