Since its introduction in 1993, the 49ers have used the franchise tag designation just six times on five different players. The tag, which teams can only use once a year, binds a player to that team for an additional year. It guarantees the player a one-year contract for an amount no less than the average of the top five salaries at the player's position or 120 percent of the player's previous salary. Whichever is greater.
The following are the 49ers players that are scheduled to become unrestricted free agents on March 9.
WR Anquan Boldin
G Alex Boone
RB Reggie Bush
K Phil Dawson
NT Ian Williams
