Harry (head) was on the field for practice Wednesday, Zack Cox of NESN.com reports.
Meanwhile, Nelson Agholor (head) and Kendrick Bourne (reserve/COVID-19 list) were absent from the Patriots' first Week 16 session. If neither or both players aren't cleared to play Sunday against the Bills, Harry -- assuming he's available -- would be in line for added snaps alongside Jakobi Meyers.
