The Denver Broncos lined up with just 10 men on the field for the first snap of Sunday’s 38-10 over the Detroit Lions at home to pay tribute to the late Demaryius Thomas.

The receiver spot where Thomas once regularly lined up for the Broncos was left open and Denver let the play clock wind down for a delay of game. The Lions declined the penalty as fans loudly chanted “D.T., D.T.” The atmosphere in Denver was full of memories of Thomas, who was found dead on Thursday at age 33 at his home in Roswell, Georgia.

Reports indicated Thomas was dealing with seizures. Police said Thursday his death might have resulted from a medical issue.
