The Minnesota Vikings, who could be in the market for depth on their defensive line, have interest in signing Canadian Football League DE Phillip Hunt, a source said. Two of Minnesota’s top three pass rushers, Ray Edwards and Brian Robison, are unsigned for next season.

Hunt, who worked out for the Vikings on Dec. 18, also worked out for the Cleveland Browns (Dec. 16), Houston Texans (Dec. 28), New England Patriots (Dec. 20) and Philadelphia Eagles (Dec. 14). The Vikings also recently worked out six other CFL players.

CFL players were prohibited, by rule, from signing with NFL teams until Jan. 3, which is when the NFL regular season ended. The window to sign CFL players expires on Feb. 15. The CFL free agency period starts the next day.

Hunt, who posted 19 sacks over the past two seasons with the Winnipeg Blue Bombers, went unselected in the 2009 NFL Draft. He signed with the Browns a few days after the draft but was waived during the preseason. He signed with the Blue Bombers in September of that year. He was the CFL’s top pass rusher this past season with 16 sacks.

The defensive lineman out of the University of Houston is the latest sack artist to come out of the league north of the border.

Miami Dolphins second-year OLB Cameron Wake was a former two-time CFL player of the year. He finished third in the NFL during the 2010 season with 14 sacks and was selected to the Pro Bowl.
