Greg Childs tears both patellar tendons

Vikings rookie WR Greg Childs tore the patellar tendon in both his knees in practice on Saturday.  We've never heard of this happening.  Childs also tore the patellar tendon in his right knee back in college.  He's obviously done for 2012, and his football future is on life support.  Childs was considered the favorite to start out wide for Minnesota during Jerome Simpson's 3-game suspension to start the season.  That job will now likely go to Michael Jenkins, who won't carry much fantasy upside at all.
