Ricky Jean Francois, a backup nose tackle with the 49ers, is a backup no more.
Jean Francois agreed to terms Thursday with the Indianapolis Colts on a four-year, $22 million contract, according to Philadelphia-based reporter Adam Caplan. Jean Francois visited the Philadelphia Eagles before taking a flight Wednesday night to Indianapolis.
On Wednesday, the 49ers signed defensive lineman Glenn Dorsey as a potential starter at nose tackle. Isaac Sopoaga, a starter for the 49ers the past five seasons, signed with the Philadelphia Eagles on the first day of free agency.

Jean Francois played in all 16 games the past three seasons for the 49ers with five career starts. He started one game last season in place of Sopoaga, and he started twice in place of Justin Smith at right defensive end.
Jean Francois recorded a career-best 51 tackles (27 solo), according to the 49ers' film review. He had a career-best two sacks while playing 27 percent of the team's defensive snaps.
Earlier this week, the 49ers signed third-string nose tackle Ian Williams to a two-year extension through the 2015 season.
