Kincaid (knee) wasn't participating in Thursday's practice, Alaina Getzenberg of ESPN.com reports.
Kincaid, who sustained a knee injury during the Bills' Week 10 win over the Colts, also sat out practice Wednesday, so what the tight end is able to do Friday will loom large regarding his status for Sunday's game against the Chiefs. If Kincaid is unavailable this weekend, Dawson Knox would step in as the Bills' top tight end and could see more involvement in the passing game.
