The practice squad revolving door took another spin on Friday when the Minnesota Vikings swapped one defensive end for another.

The Vikings waived Ernest Owusu from the practice squad to make room for George Johnson.

Johnson, formerly of the Tampa Bay Buccaneers, went undrafted out of Rutgers during the 2010 NFL Draft. During his three seasons in the league, the 6’4’’, 265-pound end has seen the field during nine games. In that time, he has amassed seven total tackles.

After seeing limited action early last season, Johnson spent the majority of the year on the Injured Reserve list following a knee injury. He played in five games for the Buccaneers in 2012 before being released on November 1.

More than anything, Johnson will provide depth along the line. The former Scarlet Knight does, however, offer some upside as a project who could eventually develop into a contributor.

Owusu is an undrafted rookie out of Cal who has spent the last couple months on and off of the Vikings’ practice squad. Signed by Minnesota shortly after the conclusion of the 2012 NFL Draft, he failed to survive final roster cuts back in August. He was later re-signed to the practice squad, and has been waived five times since then. With the addition of Johnson, it’s unlikely that the Vikings will re-sign him anytime soon.

Just another insignificant roster swap as the Vikings attempt to avoid a mid-season letdown.
