The wide receiver took just two of the seven passes that quarterback Peyton Manning targeted at him, including a potential touchdown pass.
Last year's leading touchdown scorer for the Broncos told the team's website: "I think in the moment, it's kind of, 'Oh, crap. Why did that happen?' And then you've got to flush it quickly because when you play 70-plus plays a game, you've got to play them one at a time.
"There were way too many mistakes personally. Fortunately I've got a lot of great teammates that picked up the slack and played very well. But I can't let that happen again, it's embarrassing to myself.
"For me, it's a big self-confidence booster, knowing that a guy like [Manning], your quarterback, has that trust in you and knows that you have that ability. It makes me want to work that much harder and make sure that I show up and prove that."
The Broncos, who play the New York Giants this weekend, went on to beat the Baltimore Ravens 49-27 last Thursday.
