As the N.F.L. safety Damar Hamlin remained in critical condition on Thursday after he went into cardiac arrest during a game earlier this week, the rest of his Buffalo Bills teammates were planning to be back at practice ahead of their next game.
On Monday night, Bills players watched in horror as Hamlin, 24, laid on the field and medical staff attempted to restart his heart after he had collapsed and fell backward following a routine tackle against the Cincinnati Bengals. Hamlin remained on the field for 10 minutes before being transported to the University of Cincinnati Medical Center.
