The Patriots on Tuesday activated LB Dont'a Hightower off the PUP list. He had been sitting out with a right knee injury. New England re-signed him in the offseason to a multi-year deal, however, which included $19 million in guarantees. According to ESPN's Mike Reiss, Hightower was always believed to be on track for Week 1. His return coincided with LB Elandon Roberts returning to practice after missing a few days with a rib injury. Roberts had been calling the plays and wearing the green-dot helmet on defense recently, but Hightower's the more likely candidate for that role if he's at full health. We'll see what the playing time looks like in the 3rd preseason game this weekend. Neither makes for a strong IDP candidate, but Hightower carries a high weekly ceiling when fully healthy.
