Thomas sustained the injury in the team's preseason opener versus the Titans on Aug. 8, and the injury was initially ruled a sprain. Thomas visited a specialist for a second opinion on Tuesday, and further analysis confirmed that the injury was more severe. Head coach Mike Shanahan said the torn ligament will require a minimum of four-to-five months recovery time, and that Thomas will be placed on injured reserve.
Although Thomas has never played in a regular-season NFL game, it's a devastating blow to the defense and its thinnest position is now even thinner. Brandon Meriweather, the man ahead of Thomas on the depth chart, is nine-months removed from a torn ACL, leaving Reed Doughty and DeJon Gomes as the team's only fully-healthy players at the strong safety position.
