The Ravens and Joe Flacco's agent, Joe Linta, are scheduled to begin talks on a contract extension next week at the 2012 NFL Scouting Combine, according to a league source. Baltimore is committed to keeping the 2008 first-round draft pick, whose contract expires after the 2012 season. Following the end of the season, Flacco said he felt he had proved enough to earn a new deal with the Ravens.
