Peyton Manning supports the NFL's investigation into an Al-Jazeera America report linking him to human growth hormone.

"I do welcome it. It's no news to me," Manning said after practice. "I still stand by what I said then that it's garbage from the first day that it came out, garbage today."

Manning was asked if the investigation would be a burden for the Denver Broncos ahead of the Super Bowl.

"None, no."
