Source: Smith, Ravens agree

The Baltimore Ravens are not waiting until the NFL draft to add quality depth to the tight end position.

According to a source, the Ravens have agreed in principle to a one-year, $1.5 million deal with former Philadelphia Eagle L.J. Smith. The tight end is visiting Baltimore Wednesday and could have a deal finalized by the end of the week, pending a physical.

Smith, 28, spent the past six seasons in Philadelphia, where Ravens head coach John Harbaugh spent most of his career as an assistant. Baltimore is looking for an additional receiving threat and depth at tight end to play alongside current starter Todd Heap, who's had several injuries in recent seasons.

Smith recorded 37 receptions for 298 yards and three touchdowns for the Eagles last year. A former second-round pick in 2003, Smith has 231 career receptions in 85 games. He also had visits with the Atlanta Falcons and Detroit Lions.
