The Raiders expect he will be ready to go for training camp although it is unlikely he would participate in any of the off-season activities.

The 32-year-old defensive lineman was signed as a free agent this off-season from the Texans. He started all but two games the past five seasons in Houston and was a Pro Bowler in 2011. His 2013 season was on par with his career production with 30 tackles and 5.0 sacks.

Smith signed a 2-year, $9 million deal with the Raiders in March and is expected to start at right defensive tackle alongside Pat Sims and add some much needed pass rush to the Raiders defense.
