Can Ravens replace Pitta? (UPDATE)

UPDATE: Aaron Wilson of the Baltimore Sun reports that the Ravens have signed Visanthe Shiancoe to a one-year, $940,000 deal, and that Shiancoe was already on the field wearing No. 81 for the Ravens.

Dennis Pitta's injury, a dislocated hip that will knock him out for the entire 2013 season, means that Joe Flacco will be a throwing to a lot of new faces this season. With his tight end sideline and last year's top wideout Anquan Boldin now in San Francisco, the Ravens must replace more than one-third of their receptions from last year's Super Bowl team.
