Hamlin, the Bills safety who collapsed during the two teams’ previous meeting, was on hand to support his teammates in the A.F.C. divisional round game.
ESPN told viewers that players were given five minutes to warm up after Hamlin was taken off the field. The N.F.L. denied that. On Sunday, Commissioner Roger Goodell addressed the question.
The Buffalo Bills player Damar Hamlin collapsed in cardiac arrest on the Bengals’ field last week. He is doing better and, with a win over the Ravens, so are the Bengals.
