The Vikings officially announced the signing of defensive end Lawrence Jackson today, which we already knew about last week, but Jackson isn’t the only veteran free agent that inked a prove-it deal with the Vikings on Monday.

The Vikings signed cornerback Jacob Lacey to a one year contract with the Vikings, for which financial details were not immediately available, but it is expected to be minimal.

Lacey, who turns 26 next month, was an undrafted free agent signed by the Colts in 2009. He played three seasons with Colts, starting 27 of those games with five interceptions, two returned for touchdowns, 21 defended passes, three forced fumbles, one recovery, and 158 total tackles.

He then moved onto Detroit for one season where he had nine starts, 29 tackles, four defended passes, and an interception.

Assuming Chris Cook and rookie Xavier Rhodes win the starting corner spots on the outside, Lacey figures to battle in training camp to become the team’s nickel or dime back.  That battle will primarily be against the likes of Josh Robinson, A.J. Jefferson, Brandon Burton, and Marcus Sherels.

One can’t help but notice that both of these recent free agency acquisitions wore Lions helmets last season who the Vikings not-so-coincidentally face in week one of the regular season.
