When the Arizona Cardinals got their roster down to 53 players, we knew it probably would not stay that way. The fact that the team kept a whole bunch of defensive backs seemed to indicate that a trade was going to happen at some point -- perhaps for an offensive lineman. It turns out that a trade was in the works, and cornerback A.J.Jefferson is set to become a member of the Minnesota Vikings.

Kent Somers tweeted the news, citing a league source, but there was one tweet that topped that -- Jefferson himself.

Jefferson, who was originally undrafted, showed quite a bit of potential a year ago in training camp. He earned the starting job coming out of camp and was one of the team leaders in tackles.

With the addition of William Gay and Jamell Fleming in the offseason, it was known that there was going to be at least one talented defensive back left off the team. The team managed to work it so that it could get some compensation. The teams have not announced the trade, as physicals are probably pending.

His trade means that Michael Adams once again has fought his way onto an NFL roster.

If no player comes in return, we can expect to see the Cardinals active on the waiver wire.

Jefferson will be missed. He was physical and talented. He seemed to be worried about letting his guy get behind him, sometimes meaning he left too much space in front of him. But he was a sure tackler and was a solid contributor on special teams. He will match up well with the big receivers in the NFC North.

What are your thoughts on the reported trade?
