Keene is active for Sunday's game against the 49ers, Mike Reiss of ESPN.com reports.
Fellow rookie tight end Devin Asiasi was made a healthy scratch Sunday, which paves the way for Keene to make his NFL debut in Week 7. Though Keene posted modest volume while at Virginia Tech, his per-target efficiency was notable thanks to his strong work after the catch. A wait and-see-approach is in order here from a fantasy perspective, but perhaps Keene can provide the Patriots offense with a lift in his first game action as a pro.
