"Dallas Clark is on his way to Baltimore right now," Harbaugh said.
A former Indianapolis Colts Pro Bowl selection, Clark, 34, has strong connections to the Ravens through his relationship with offensive coordinator Jim Caldwell. Caldwell coached him in Indianapolis where Clark was one of quarterback Peyton Manning's favorite targets.

Clark should provide a veteran, sure-handed presence for the Ravens' injury-riddled tight end position following a season-ending fractured and dislocated hip for starter Dennis Pitta and a slightly torn hamstring that has sidelined Ed Dickson.
Although the Ravens have veteran Visanthe Shiancoe under contract, Clark is coming off a strong season with the Tampa Bay Buccaneers where the 6-foot-3, 252-pounder caught 47 passes for 435 yards and five touchdowns. Shiancoe is a former Minnesota Vikings and Morgan State star who didn't catch a pass last season during an injury-plagued year with the New England Patriots.
For his career, Clark has 474 receptions for 5,322 yards and 50 touchdowns for an average of 11.2 yards per reception. He won Super Bowl XLI with the Colts.
During the 2009 NFL season, Clark caught a career-high 100 passes for 1,106 yards and 10 touchdowns.
Clark is a 2003 Colts first-round draft pick from Iowa who's represented by Cleveland-based agent Neil Cornrich, who has long-standing relationships with the Ravens organization. Cornich also represents Ravens Pro Bowl offensive guard Marshal Yanda, who signed a five-year, $32.5 million contract extension three years ago that included $10 million in guaranteed money.
