Analysis: The Patriots fear they have lost their top pick (third round, 83rd overall) in the draft for the entire season, league sources told ESPN on Friday. Rivers was injured on a kickoff coverage drill Wednesday in a joint practice with the Texans. Rivers, who was projected to be part of a rotation at defensive end, played 41 snaps in last Thursday night's preseason opener against the Jaguars. He had 41 sacks at Youngstown State, including 14 as a senior.
