Winter storm prevents Andrew Luck's visit to Letterman

Sometimes, it's a blitz. Sometimes, it's a blizzard.

Colts quarterback Andrew Luck is postponing an appearance on "Late Show with David Letterman" because of a winter storm that's expected to blanket New York City with 20 to 30 inches of snow.

Luck had been scheduled to be a guest on Tuesday's episode, with actor Oscar Isaac, star of new film "A Most Violent Year," and rock duo Drenge.

Indianapolis native Letterman is scheduled to retire from his late-night talk show after its May 20 episode.

Luck visited "Late Show" in April 2012, when he was in New York for the NFL Draft.

"I was more nervous to come out here than to go meet commissioner Goodell," Luck told Letterman.

"Well, that's how we like it," the 1965 Broad Ripple High School graduate responded.

In February 2013, Luck made an appearance in "Late Show's" Super Bowl commercial.

Luck spent his Sunday in Arizona, where he threw for two touchdowns in the NFL Pro Bowl.
