Kincaid (knee) isn't practicing Thursday, Alaina Getzenberg of ESPN.com reports.
Kincaid was also deemed a non-participant for Wednesday's walk-through practice, so what he's able to do Friday will loom large in determining his status for Sunday's game against the Browns. If Kincaid isn't available this weekend, Dawson Knox would likely be in line for elevated snaps as the Bills' clear top tight end.
