The Minnesota Vikings finalized their 53-man roster at approximately 8 PM Central time. Shortly after that, they apparently made their first transaction since finalizing the roster.

According to his own Twitter account, the Arizona Cardinals have traded cornerback A.J. Jefferson to the Minnesota Vikings.

Just found out I'm being traded... God works in mysterious ways. #thegrassisgreener

I'll be completely honest. . .I don't know a heck of a lot about A.J. Jefferson. I've heard his name a couple of times, but I don't know much about him. (I've put out some feelers to our friends at Revenge of the Birds to see if they can fill us in a bit.)

What I do know about him. . .i.e. "what I can find from looking around the internet". . .is that he went undrafted in 2010 out of Fresno State University, and signed with the Cardinals as a free agent. He's a bigger corner, measuring in at about 6'1" and around 195 pounds. He appeared in only two games with the Cardinals as a rookie, but played in all 16 games in 2011, including getting seven starts. He had one interception and 12 passes defended (including two in the Cardinals' Week 5 match-up against the Vikings), and also notched 66 tackles. He has some ability on returns as well, which is probably just as intriguing to the Vikings as his ability to play corner at this point.

So, hopefully we'll learn more about A.J. Jefferson in the coming days. . .and hopefully he'll fit in well with the team. At 24 years of age, he certainly fits in with the Vikings' youth movement.
