Von Miller has said that he is devastated by the Denver Broncos' loss to the Baltimore Ravens in the NFL playoffs.
The linebacker did not move or speak for 45 minutes following the overtime defeat on Saturday.
The 23-year-old told reporters: "I'm still not ready to let it go. It's just all season, it took a lot to get to this point. To walk away from it on that note, I can't even put it into words. It's devastating.
"I've had my losses before. I've won some, too. But I think this loss definitely is different from the rest of them.
"I think it will burn a little bit throughout this off-season, throughout training camp next year and when we get started next year. All adversity does is build character. I'm going to take this head-on and attack this off-season."
The defeat was the Broncos' first loss in 12 games.
