Denver Broncos running back Knowshon Moreno was filmed in floods of tears during the US national anthem before Sunday's clash with Kansas City Chiefs.
The 26-year-old produced two huge streams from his eyes as the camera panned to him - but he went on to reveal that this was not a one-off show of emotion.
"The emotion always gets to me," Moreno told Yahoo Sports after the Broncos moved to 10-2 in the AFC West standings. "I am just thinking about everything in general through your whole life, just balled up into one."
The outpouring of emotion clearly benefitted Moreno, who went on to help his side record a 35-28 victory over the Chiefs.
"Yeah, it helps me," Moreno added. "Sometimes I don't even notice it, it just comes."
Moreno contributed a receiving touchdown as the Broncos bounced back from last week's last-gasp defeat to the New England Patriots.
And his friend and colleague, Montee Ball, believes the tears are a sign of great strength rather than weakness.
"The [tears] are actually toughness," Ball told reporters. "I see it all the time. He does it in practice and he does it in games. It is all heart, it is his passion for the game. It is massive. We all feed off that energy. A lot of stuff sets him off. He just brings that energy when we need it."
