Suh was released by the Miami Dolphins shortly after the beginning of the league year on March 14. He's reported to have met with the New Orleans Saints, Tennessee Titans, and Los Angeles Rams since then.
The 31-year-old remains one of the best in the game at his position, ranking as Pro Football Focus' No. 5 interior defender last season.
He would solidify a Raiders line that's built around defensive end Khalil Mack.
