Defensive lineman Richard Seymour and kicker Sebastian Janikowski highlight a group of prospective free agents that the Raiders will try to retain for 2010.
Davis traded a 2011 first-round pick to the New England Patriots for Seymour shortly before last season started.
Oakland could use the franchise tag on Seymour, which would obligate the Raiders to pay him $12.398 million for 2010.
The franchise tag guarantees a player the average of the top five salaries at his position for the previous season.
Their other options would be a long-term extension, or letting him walk in free agency.
