Vikings coach Leslie Frazier described S Tyrell Johnson's hamstring injury as "significant" at his Monday press conference. It sounds like Johnson could be dealing with a season-ending ailment. Minnesota's primary reserve at safety, Johnson has tallied 28 tackles and zero interceptions. Mistral Raymond should be first in line for an increase in snaps.

Vikings S Tyrell Johnson left Sunday's game in the second quarter with a hamstring injury. Johnson tweaked his right hamstring. He's considered questionable to return.

Vikings S Tyrell Johnson was arrested on a fourth-degree DWI charge early Tuesday morning. A fourth-degree DWI is a misdemeanor. Johnson has been a disappointment since being selected with the No. 43 overall pick in the 2008 draft, failing to beat out for Jamarca Sanford for the starting job this summer. He'll likely avoid league discipline as this is his first violation of the personal conduct policy.
