NEW YORK (AP) - Super Bowl MVP Joe Flacco tells David Letterman the time has come for him to start talking contract with the Baltimore Ravens.

The quarterback led the Ravens to a 34-31 victory against the San Francisco 49ers on Sunday in the Super Bowl at New Orleans. Flacco completed a remarkable postseason run with 11 touchdown passes and no interceptions in four games. He is about to become a free agent.

Less than 24 hours after winning the Super Bowl, Flacco appeared as a guest on CBS' ``Late Show.'' The show will air Monday night.

Flacco turned down an extension offer from the Ravens last year. He says Ravens owner Steve Bisciotti told him when the season was over he could come to his office and pound on his desk.
