Jim Nantz didn't mention a report linking Peyton Manning to shipments of human growth hormone during CBS' telecast of the Denver Broncos' Week 17 game.

Mike Francesa asked Nantz earlier in the week if he and Phil Simmons would discuss the Al Jazeera report.

"No, why would we? If we talk about it we only continue to breathe life into a story that on all levels is a non-story, Nantz said. "Why add another layer to it?"

The NFL is investigating the report of HGH.
