Patriots believe top draft pick Derek Rivers has season-ending injury, report says

The Patriots believe defensive end Derek Rivers, their top draft pick this year, will miss his rookie season with a knee injury, ESPN reported Friday. NFL Media later reported an MRI showed Rivers tore the anterior cruciate ligament and sprained the lateral collateral ligament in his left knee. Rivers, a third-round pick out of Youngstown State, was injured on a kickoff coverage drill during the Patriots' joint practice with the Texans on Wednesday in West Virginia.
