Raiders TE Darren Waller (hamstring) has been activated and is now eligible to play vs. the Patriots on Sunday. He's been out since Week 5 with a lingering hamstring injury. Waller averaged 6.0 targets, 4.0 catches, 44 yards and .3 TDs over the first 4 weeks of the season, ranking 12th among TEs in half-PPR points during that stretch. Consider him a low-end, risk/reward TE1 in Week 15 fantasy lineups.
