The network said Roenick, who has been an analyst with NBC Sports since 2010, will be suspended without pay.
Roenick made the comments about fellow NBC Sports personalities Kathryn Tappen, Patrick Sharp and Anson Carter during a Dec. 18 appearance on the "Spittin' Chiclets" podcast.
His remarks included a story about a vacation to Portugal he took with his wife, Tracy, and Tappen, who he said are good friends.
“I play it off like we're going to bed together every night, the three of us," he said during a story referencing when a resort worker asked about the arrangement. “If it really came to fruition, that would really be good, but it's never going to happen."
He also called Tappen “one of the most professional sports personalities I know" and praised Sharp as “one of the greatest, greatest guys on the planet."
Later in the podcast, Roenick called Sharp beautiful, saying: “I'd have to think about it if he asked me. ... I wouldn't say no right away.”
“It's good to have a beautiful face that talks well, that knows the game because it's totally the opposite when me and Anson get on there,” he said.
He added that Sharp has been "great for NBC."
