Vikings placed S Tyrell Johnson on injured reserve with a torn hamstring, ending his season.
Johnson suffered the tough injury in Week 12. With Husain Abdullah also done for the year, Mistral Raymond will likely take over at free safety, leaving the Vikes with second- or third-teamers at three positions in the secondary. A bust as the No. 43 pick in the 2008 draft, Johnson will reach free agency in 2012.
