Sources: Rodger Saffold to Raiders

Former St. Louis Rams tackle Rodger Saffold has reached agreement on a five-year, $42.5 million deal that includes $21.5 million guaranteed with the Oakland Raiders, league sources told ESPN NFL Insider Adam Schefter and ESPN NFL Insider Adam Caplan.

Saffold will make $16 million in the first year and $27.65 million in the first three, according to sources.

The Raiders moved quickly to replace left tackle Jared Veldheer, who agreed to a five-year, $35 million deal with the Arizona Cardinals, league sources told Schefter.

Saffold came to the Rams with the expectation of handling the left tackle job after the team used a second-round draft choice on him in 2010. Injuries kept Saffold from becoming the reliable starter the Rams envisioned at the time.

In four seasons with the team, the 25-year-old Saffold played in 47 games with 44 starts. Knee, pectoral, shoulder and head injuries are among the various ailments that have kept him from staying on the field consistently.

Last season, Saffold's greatest value came in his versatility as he began the season at right tackle, stepped in on the left side after Jake Long suffered a knee injury and also started six games at right guard. Although Saffold played well at tackle, he flashed Pro Bowl promise at guard.
