The Bills said Hamlin was part of the team's Friday morning message via video call.
"Damar Hamlin FaceTimed into our team meeting today to talk to players and coaches. What he said to the team: 'Love you boys.'"
Hamlin, 24, is breathing on his own for the first time since going into cardiac arrest during Monday night's game in Cincinnati. The Bills said Hamlin addressed the entire team Friday via FaceTime.
Doctors at the University of Cincinnati Medical Center said Thursday that Hamlin had made "substantial" progress although he remained in the intensive care unit, his family by his side.
