According to the Associated Press, Boone passed his physical with the team Monday. The 49ers requested a roster exemption to allow Boone to get up to speed with the team without costing them a capable player in the interim. San Francisco will likely get the exemption from the league. Players coming off suspension get similar roster exemptions as well.
The 49ers will need to make a roster move eventually to add Boone to their 53-man roster before he will be eligible to play.
San Francisco’s first-string offense struggled throughout the preseason, which surely gave Boone some added leverage in negotiations. The 49ers open the season against the Dallas Cowboys on Sunday.
