The Raiders will make the first high-priced splash in free agency.
According to NFL Media's Rand Getlin, the team will ink former guard/tackle Kelechi Osemele to a deal. Both sides have already agreed to the pact in principle. Terms of the deal were not available and cannot be finalized until Wednesday.
Osemele, who will turn 27 before training camp, is a five-year veteran considered a consensus top-five free agent this offseason. He was listed as No. 3 overall on Around The NFL's top free agents list. Osemele was a second-round pick in the 2012 NFL Draft and has started 51 games over the past four seasons.
