Tom Pelissero of 1500 ESPN Twin Cities reports that Childs suffered a "significant" injury to both knees and is "almost surely" done for the season. Considered a potential future first-round pick before rupturing his patellar tendon as a junior at Arkansas, Childs' draft stock plummeted playing with a hitch in his gait as a senior. He was available to the Vikings in April's fourth round.
Per Pelissero, the early fear is that Childs tore both patellar tendons.
The Vikings were hoping Childs would emerge as their starting split end early in the season, during Jerome Simpson's three-game suspension. They will have to look elsewhere now. Expect G.M. Rick Spielman to scour the free-agent and trade markets at receiver this week.
